Konica M-Hexanon 28mm f/2.8

20160524_192703

The 28mm M-Hexanon, like the its focal length, occupies a strange space that is neither here nor there. I have never had good luck with 28mm lenses, if only because the angle is a little wide to be comfortable for close shots of people and a little narrow for some of the landscapes I shoot.

Only on the verge of selling mine (for lack of use since way back when I had an M8) did I shoot a bunch of tests with an M typ 240. This particular lens had been recollimated to be at exactly Leica spec (most lenses made before the M8 were not set up to hit the center of a flat sensor).

This piece will not editorialize much but instead show it like it is. Which is quite good, far better than I had remembered.

First, the obligatory “how sharp at a meter” exercise. This is f/2.8.

Next: does it shoot good pictures of children? Yes.

E poi – how is the bokeh? Strangely, it’s actually really good, especially for a wide lens. Here is the sequence f/2.8, 4, 5.6, 8.

Sunstars? Got ’em too. Here is f/2.8-8 (clockwise):

Will the real infrared photography please stand up?

b-w_ir_filters

The strange thing about infrared photography is that it represents a very small piece of photography in general, but there is apparently no space in photography so small that it can’t support some form of snobbery. And in infrared photography, it is the idea that there is “near” infrared versus “true” infrared. Not only does this convey a false sense of exclusiveness to people who shoot 850nm and up, it’s also not accurate.

When you shoot a normal camera in daylight, there is a small amount of infrared contamination – it’s about 10 stops less than daylight, or coming in at 1/10 of a percent or 1/1024. Tiny, even on something with big infrared contamination like a Leica M8. So any particular shot is overwhelmingly lit by visible light.

A dark red filter (RG630, 091, 8x, #29, etc.) flips the equation: the average blockage of visible light is 3 stops, or 75%.The reality is that most skylight scenes are predominantly blue, and this filter cuts a lot more than three stops. Even if you are shooting objects that are middle grey, these filters reject 75% of all light – meaning that when you shoot them on a camera with no other IR rejection, deep red and infrared light make up 75%+ of the light. The false color you are obtaining is infrared light that is still being blocked in part by green and blue squares on the Bayer filter on the sensor.

The case for the “near” classification is even weaker with the 695-720nm filter (RG695, 092, R720). First, consider that wavelength ratings on filters are at the 50% mark. So a 720nm filter really starts passing 100% of its light around 750nm. On a short exposure, which you will see is commensurate with a normal visible-light exposure, infrared light is providing almost all of the illumination.

Going the other way, “true” infrared is not that advantageous – and may not be something to commit to in an IR conversion. First, even though the Bayer filter does not affect 830nm+ light, the decoding algorithm in your camera still compensates for it. So if you dump the RAW file into DCRAW, what comes out still has something of a checkerboard pattern. Second, the false color effects generated by mid-band IR actually allow for more contrast control because there are multiple channels of useful information (and with 850nm+, you really need this, since everything likes to come out bright white in sunlight, especially around dusk). Eliminating this effect means that you have less ability to rebalance the tones in a scene.

None of this is to say that it’s good to meet one form of snobbery with another technical one. But let’s just keep the infrared world big, okay?

50mm f/1.5 Zeiss Sonnar (1937): first

20160106_191418

Above: Zeiss Jena 5cm f/1.5 Sonnar (prewar; 1937 example of the 1932 design) on a Leica M typ 240 with an Amedeo dedicated 50mm adapter. This particular lens is almost 80 years old.

1. The story

The derivation of the trade name “Sonnar”(which may have less to do with Sonne than being a portmanteau of Sontheim am Neckar) reminds one of the the way that the Mr. Sparkle is a joint venture of the Matsumura Fishworks and the Tamaribuchi Heavy Manufacturing Concern. Be this as it may, the Sonnar had but one goal in life: crush Leitz’s fast lenses in an era where ISO 12 film was the norm. And that it amply did. Even today, the performance of this uncoated lens is impressive.

When the Sonnar arrived in 1931 (f/2.0) and 1932 (f/1.5), the Tessar (or Elmar) was the gold standard in normal lenses: a well-corrected triplet that, in an era lacking anti-reflective coatings, sneaked in a little more correction by cementing two pieces of glass together. When it came time to exceed f/2.8, though, the real competition began:

  • In 1889, Paul Rudolph, working for Carl Zeiss, determined that the best balance of contrast, correction, and cost was a three-element lens called an anastigmat (trade name: Protar).
  • In 1895, Rudolph invented the Planar, which was a highly-corrected symmetrical lens. It was shelved soon thereafter, no doubt on account of the low contrast that occurs with many air-to-glass surfaces.
  • In 1902, Zeiss released the Tessar, which provided more correction than an anastigmat (by adding a fourth element glued to the the third) without increasing the number of air-glass surfaces. The Tessar was technically inferior to the Planar, but it did not have the two extra air-glass surfaces (each robbing 10% of the light, compounded).
  • In 1925, Max Berek modified the Leitz Elmax, which had a 1-1-3 (cemented) arrangement into the Elmar, which bore a heavy resemblance to the Tessar, allowing for a good 35mm-format lens with fewer elements and less assembly labor.

In parallel universe (but still orbiting around Zeiss)

  • In 1916, an American (Charles Minor) started adding elements to the triplet, but just in the front. The result was the Gundlach Anastigmat, which had a blazingly fast f/1.9 aperture. The contemporary ads show that this was actually a cine lens.

  • In 1922, Ludwig Berthele, working for Ernemann (of Ermanox fame) continued elaborating this into the Ernostar, which became on of the first plate lenses to hit f/1.8 (in 1924).

  • In 1926, Zeiss bought Ernemann and acquired Berthele in the deal.
  • In 1931, Berthele made the first f/2 Sonnar, which was a new lens with an old name. It was for 35mm format and had a 1-3-2 arrangement, with the second and third group cemented together.
  • In 1932, he made the f/1.5 version, which added an extra element to the rear group.
  • In 1936, caught off-balance, Leica licensed the Xenon, a symmetrical Double-Gauss design from Schneider, licensed in turn from Taylor-Hobson in England (the Series 0), in turn had been cribbed from the 1896 Planar.
  • In 1944-1945, the Zeiss plants were bombed back to the stone age.
  • In 1949, the Xenon was updated with coagulation-style lens coatings and became the Summarit.
  • In 1950, the Zeiss-Option Sonnars came out with a new computations.

The circle was now complete: the entire high-speed lens space was dominated by Zeiss designs and would continue to be – for pretty much all time. When you stop and think about it, until the advent of things like the 50/1.4G Nikkor, the history of high-speed lenses had been nearly nine decades decades of Sonnar and Planar clones.

Why did the Sonnar do so well? It’s not so complicated. It all boiled down to the number of air-to-glass interfaces. The classic triplet (the anastigmat) represented the best balance between correction, contrast, and cost. But adding more elements (to get more correction) meant more air-glass interfaces. And that meant less contrast and more flare. Zeiss increased the correction by cementing additional elements together to make a total of three groups. Leica could not do this because it did not have the intellectual property rights to do so. During WWII, Zeiss dabbled in coating its super-speed lenses, but it was not even really necessary given the Sonnar’s high transmission.

2. Using one today

These days, the Contax rangefinder is almost dead, 35mm film photography has gone all “Tony-Bennett-in-the-late 1990s,” and so the only place you’ll likely be using one of these is on a Leica body. Fortunately, it’s pretty easy to do. You just need the appropriate adapter. These are not particularly expensive for APS-C (although they do incorporate focusing helicoids); they are more expensive for Leica cameras because they need a mechanism to translate the movement of a 52.3mm lens to a camera whose rangefinder mechanism wants a 51.6mm normal lens (how two German companies known for their precision could get so sloppy about what constituted a “50mm” lens is baffling – but being a big-name German optical company means never having to say you’re sorry….).

By far, the best adapters for Leicas are made by Amedeo Muscelli, and of those, the best is that dedicated adapter for Contax 50mm rangefinder to Leica M. This is  not the usual lens with the reproduction of a Contax helicoid and focusing scale; rather, combines with the lens to make a unit that looks a bit like an old Elmar (allowing, of course, for the streamlined – dare we say phallic) shape of a Sonnar. The dedicated adapter focuses in the same direction as a Leica, at almost the same rate of distance change per unit of turn, and it has a lever, which can be critical if you are using a collapsible Zeiss lens (since with a traditional adapter, you are grasping the lens barrel to focus – something you can’t do with a collapsible lens). When your lens is dialed in, this adapter focuses amazingly accurately right down to 0.6m – a lot closer than any Contax did.

And how do you dial one in? If your lens is front-focusing, the simple answer is to remove the lens cell from the Contax barrel and unscrew the rear group slightly. It is never more than 1/4 turn, and you can maintain the setting by wrapping the threads of the rear group in Teflon tape and screwing it back in. Back it out about a 1mm (circumferentially) at a time, and check the focus on near and far objects. Do note that where a Sonnar has a lot of focus shift, you’re going to have to choose whether to

  1. Have the lens front focus at f/1.5, reach focus at f/2.8-4 ,and hit focus at f/5.6 and smaller
  2. Have the lens focus dead-on at f/1.5, miss at f/2-4, and become usable again at f/5.6 and on.

3. Observations

The first observation is that finding a prewar f/1.5 Sonnar that is not totally trashed is not particularly easy. Fortunately, at least cleaning marks are not an issue on uncoated lenses unless someone used Soft Scrub as an optical cleaner. Which does happen from time to time.

The second is that in the central part of the frame, this lens is very, very sharp. It has decent performance at f/1.5 if you optimize for that aperture, loses precise focus from f/2.8-f/4, and comes roaring back at f/6.3. If you keep with the original collimation (or an approximation of it, you get really sharp pictures around f/2.4, getting better through f/8.

The third is that the coatings on postwar Sonnars are not moving the ball much in terms of performance. Because this was the last fast Sonnar I obtained, it’s easier to compare this to the 1961 Carl Zeiss version. The 1937 model performs similarly in most ways. It is very slightly softer, with contrast that is almost at the level of a 1977 Jupiter-3.

Flare is only slightly improved by coatings, and they do not resolve the “rainbow circle” flare that afflicts every Sonnars (even multicoated Sonnetars) when a point light source is just out-of-frame. The one unique failure mode is strong side lighting (from the looks of it between 75 and 90 degrees to the lens axis), which can cause a veil across the entire surface. This also happens to a lesser degree with postwar Sonnars and copies, just not quite to the same degree.

Overall performance is strikingly close to the postwar, if you allow for slightly improved spherical aberration on the older lens. The postwar version is a tiny bit sharper, but seems clear that this comes at the expense of bokeh, which goes from smooth disks to ringed disks. If you care about that stuff.

4. Roy Batty

The f/1.5 Sonnar was the proverbial candle that burned twice as bright, and by 1962 it was essentially extinct. The “twice as bright” part is doubly applicable to the 1960-1962 Car That it was so widely copied in the postwar era is puzzling. Granted, German patents were handed over to the Japanese, but in terms of sheer performance with coatings, there were already better lenses to copy (like the Xenon). Canon, Nikon, and Zunow all made their own versions. The Soviets made one too. Perhaps there was a “prestige” element to the Contax that was desirable to copy (though you would not have the all-important brand name). Or perhaps there was something about the mechanical design of a 3-group lens such that the cost of machining extra parts for 6 groups cost more than triple-cementing rwo groups. The world may never know. The fetishization of the Sonnar did not really get started until the mid-2000s and by then, it was based more on imperfection and “look” than a perception that it was actually better.

Conclusion

The prewar f/1.5 Sonnar is a worthy lens, though its relative scarcity does not exactly make it a value leader compared to postwar variants. As with any 50mm Sonnar, as long as you take care to control the placement of light sources, it can be another creative tool, if not a broader-use lens.

Canon 50mm f/1.2 LTM: not screwmounting around

L1000109_DxO

As you contemplate modern lenses, It is difficult to associate these optics with the proud civilizations that created them: Tokyo, Rochester, Sendai, Jena. They worshipped image quality, because it is strength that makes all other values possible. No picture survives without it. Who knows what delicate objective lenses have died out of the world, for want of the strength to continue. 

It’s a long way from the Canon 7sz to Andre Agassi, from the Serenar to the EOS Kiss Merkur XR4ti (…or whatever the amateur model of the week is). Canon used to be a hard-core producer of Leica knockoffs, many of which were more functional, convenient, and reliable than the rickety prewar designs that Leica kept elaborating. The Canon P was a standout, as were the VI-L and the 7 series.

The Canon 50mm f/1.2 (September 1956… can you believe that it is now almost 60 years old?) was the company’s penultimate halo lens. It came out with the VT (not Deluxe), and it would not be surpassed until 1961 with the Canon 7 and its 50/0.95 Dream Lens (from a size, weight, and cost standpoint, dream is clearly defined broadly to include nightmare). Ironically, the 50/1.2 cost more than the 50/0.95. Modern Canon lenses are quite good, but they don’t have that certain fun factor to them.

Synergies. This is a new thesis on my part, but I am starting to suspect that the M typ 240 and 246 tend to interact with lenses in ways that might not be immediately intuitive. Some lenses seem to work unexpectedly well with the color sensor (possibly the demosaic-ing algorithm accidentally boosting sharpness). Many lenses work better than expected with the Monochrom camera — likely because the color-bind sensor is not bothered as much by chromatic aberration. The “why” these things happen is probably insoluble; it is merely interesting that they do. And yes, some dog lenses do stay dogs, and some lenses have bad corners to f/8. Nulla regula sine exceptione.

Look and feel. Perhaps “Carré Otis” is the best way to express the relationship between the size of this lens and Canon’s more common 50mm lenses (2.8, 2.2, 1.9, 1.8, 1.5): generously proportioned, slightly flaky, and exhibiting certain, ahem, virtues.

The finish of the 50/1.2 is typical mid-to-late Canon that came into vogue in February 1956 with the 50mm f/1.8 mark II: a black enamel focusing ring and sandblasted chrome aperture ring and distance/DOF scale. This is much more pleasing than Canon’s contemporaneous all-black lenses (like the 35/1.5, 35/2, 100/3.5, 100/2, and 135/3.5), whose finish looks good in smaller lenses and feels chintzy in larger ones. But the affect with the 50/1.2 is solid. It will keep your M typ 240 on balance.

The focusing effort is heavy, and even the aperture turning is heavy. Unless, of course, lubricant has leaked out onto the aperture blades. The focusing pitch is very slow. Even the interesting push-button infinity lever takes a deliberate effort to dislodge. Is there a problem with any of this? No. Will you have issues tracking fast motion or switching from near-to-far subjects (or vice-versa) as if you were a D700? Yes.

Flare and use with filters. The first thing you have to remember with this lens is that you are dealing with an SLR-sized front element that sits very close to the front of the filter ring, seven elements, and single lens coatings from the mid-1950s. This isn’t going to flare, right?! Really, cleaning marks are the least of your problems here.

The big (physical) hazard with this lens is filters – as in don’t tighten down a filter without checking the clearance between the filter and the front lens element. If you want use conventional filters, you will likely need to use an empty ring as a spacer or fit a rubber o-ring around the threads on the filter. The only alternative is to use Canon RF filters, which are expensive and present a flush glass surface on the front of the lens. Not only does cabin your choices for lens hoods, it also presents ample opportunity for sidelight flare. Like the picture below (and let’s be fair – this is shot outdoors with floodlights everywhere). But be sure to use some kind of hood if you can.

L1000216

Canon filter ghosting (at f/1.2). All hell is breaking loose here (not surprising with Christmas lights a scant two feet from the lens), but it’s not all bad, given the motif:

L1000207

On balance, it is better to use a filter if you don’t want to deal with the rickety Canon metal lens caps, which never want to stay on. Just watch how you use it, and if you can space it correctly, consider an MRC.

General optical performance. On an M, at 24mp, the 50/1.2 really acts like Beauty and the Beast. At its largest aperture, it has microscopic depth of field, though with practice, you can tell where it is going to land. It does what most other super-fast spherical lenses do: it front focuses at wider apertures and settles down at middle ones. Every one of the three copies I have owned seems to have had slight differences in the midpoint of depth of field at close ranges and large apertures, which is not surprising. But this is par for the course; all fast 50mm lenses are testy on Leica rangefinders. As you start stopping down, the 50/1.2 becomes exponentially sharper. F/1.4 is light years better than 1.2; f/2.8 is orders of magnitude better yet.

Rather than dragging through every optical trait one at a time, let’s take it at f/1.2. Soft contrast, heavy vignetting, reasonable resolution of details, with a field that seems to curve at the edges toward the camera. This vignetting persists, even when the lens is coded as a Leica Noctilux. To be fair, this was more than enough for most 35mm film use. A lens like the Canon 50/1.2 would be used at night, where contrast would be high. It was not designed for thin depth-of-field fetishism. You can click on the picture below for a full-sized image.

IMG_5453

The picture at the top of this article is also shot at f/1.2. In terms of controlling bokeh, if you are into that thing, this is yet another lens where your best bokeh is achieved by (a) getting the subject as close as possible and (b) getting the background as far away as possible. Not to belabor a point from the previous article (on the MS-Sonnetar), but an easy and almost unavoidable rule of thumb is that the better a lens performs wide-open, the worse the bokeh. The list of these suppressed lenses is long and distinguished: this Canon, almost every Noctilux, the Hexanon Limited, the Nokton 1.1, the Nikkor 1.1, and basically any lens faster than f/1.4.

The next click, f/1.4, is a touch more contrasty, and is still a good setting to use in harsh nighttime conditions. Take a look at the field curvature here – there is no way the Gummi Bear wrapper should be so close to being in focus like the boys. Actually, it seems unlikely that both boys should be in focus, but there you have it. And here you also have the bokeh vibe. As in vibration.

Just for fun, below is one shot wide-open with an M8 (you can click on it to see it at full size):

20071027_185039

Stopping down to f/2 gives better results yet – and the focusing point is now exactly where you would expect it to be. And here is your bokeh test outdoors. This is essentially minimum focusing distance with a background that is 50m away.

L1001209

At f/2.8, the lens is starting to hit its stride. Especially with the M set for emulation of the Leica 50/1.2, the lighting evens up, the sharpness goes up significantly, and the field flattens a bit. Although this begs the question of getting a slower lens and shooting more wide-open, with these old lenses, you are often better off with a fast lens stopped down than a slow lens wide-open. Also, the big old glass looks cooler and makes child ward nurses less likely to think you are using some kind of super-high-tech digital camera to document medical procedures (when you’re actually just bored).

L1001716

At f/4, performance starts to max out (like the 1.2 shot, you can click on the one below to get a full-sized image). You almost go into double-take mode because a good example of the lens looks sharper than lot of modern glass. I’m thinking particularly of the 50/1.4 AF Nikkor, which the Canon crushes – and likely because the Nikon is usually tied to a somewhat limited AF system (phase detect systems seem pretty much incapable of compensating for the focus shift that occurs when a lens stops down).

L1001214

IMG_5422

F/8 is where performance starts to degrade a little bit (see the full-sized image). Sharpness starts to decline. People take on cartoonish, ascetic, or vampiric features. Bring your gloves, lightsabers, and garlic.

L1001685

Conclusion? This lens was sold as the premium lens on a lot of Canon cameras – and in some ways a “bragging rights” lens vis-à-vis Leica and Nikon. The performance at f/1.2 is reasonable but not world-beating; but given limits seen even in digital M shutters (1/4000 sec), you would rarely be trying to shoot this lens wide-open in daylight. At least absent a neutral-density filter.

The pricing of this lens is all over the place; super-clean examples (from a cosmetic standpoint) seem to command a hefty premium, but almost all will exhibit microscopic scratches (cleaning marks), and oil haze is a recurring theme (and it is fairly destructive to these lenses’ coatings). But as with a lot of things, cosmetics are not indicative of performance; you never know whether a lens has been abused over the years until you actually try it.

Be ready to poke around through multiple examples to get one that works really well; keep an open mind about the condition of the coatings; what makes these lenses flare badly has little to do with the coatings but rather with the hazards of having that really big front element.

MS-Optical 50mm f/1.1 Sonnetar: magic time

L1001353

The MS Optical Research Sonnetar is like The Life Aquatic with Steve Zissou. You either get it or you don’t, and if you don’t understand Jacques Cousteau, Willem Dafoe playing a subservient gay German, or Wes Anderson in general, there is no one who can make you like it. By the same token, if you drive Jaguars, no one with a 276hp front-drive Camry is ever going to win you over by telling you it has a higher thrust-to-weight ratio than an XJS V12 with the flying buttress hard top.

You don’t buy a Sonnetar as your only 50mm lens; in fact, you don’t even buy it as your only fast 50mm lens (and by the way, 50s should either be fast or fun – there is nothing more bland than a 50mm Summicron). The Sonnetar has strange controls for most (the rotating front barrel is exactly like using a Contax or Nikon rangefinder). It vignettes like crazy. At any distance, you can have your choice between correct focus and optical correction.

Why would anyone like it? It’s actually a big question whose only easy answer might be that when you have to shoot an f/1.1 lens in ultra-low light conditions, you pick your poison. You’re playing the limits.

N.B. All pictures shot in b/w are shot with a new Leica Monochrom (typ 246). All shots in color are with an M (typ 240). It’s absurd to change color pictures to monochrome to try to judge sharpness.

What is it? The MS-Sonnetar is the second modern revival of the 50mm f/1.5 Carl Zeiss Sonnar (West Germany, 1950s-1960s), the first one being the Zeiss ZM C-Sonnar 1.5/50mm. Why this type of lens is popular today is puzzling; when lens coatings enabled highly corrected 50mm lenses like the Planar, all of the expensive cemented groups of the f/1.5 Sonnar became obsolete. Today, the popularity of the Sonnar pattern might be in its imperfection: focus falloff in the form of field curvature and vignetting. The Sonnar yields marginally smaller and lighter overall packaging than a Planar or Double Guass, and it has slightly higher resistance to flare.

Every Sonnar revival/clone/ripoff over the past 50+ years has had its own set of strengths and weaknesses; it seems that almost none of them shows the balanced performance of the original Zeiss design. They either sacrifice sharpness for bokeh or go gaga for bokeh and live with a lot of focus shift.

The Sonnetar goes for the gusto with fewer elements and only one cemented group; a lighter, more compact barrel; and almost an entire stop of extra speed. It is the fastest Sonnar-style production lens in terms of T-stops, edging out the 50/1.1 Zunow by virtue of having fewer elements and more effective coatings.

Getting a handle on it. The Sonnetar is a very compact lens; the barrel is smaller than a 50mm Summicron, flaring out to a wider front section that takes 52mm filters (and no, full-sized B+Ws do not vignette). It’s hard to say whether it is modeled after a Zunow, a 50/1.1 Nikkor, or an Opton Sonnar. But all of them have a particular shape to them. The Sonnetar looks most like the Zunow, with the focusing and aperture rings reversed.

The frontmost ring is focus (supplemented with a small lever in the back if that’s what you want); the rearward ring is the aperture control, which smoothly adjusts from f/1.1 to f/16. Like a lot of older lenses, as the aperture numbers get higher, they get closer together (it is probably also a side effect of the Sonnetar’s super-nifty, perfectly circular German iris. But no matter in splitting hairs between f/11 and 16; you won’t be shooting there anyway.

The tough part of the ergonomics is something you’d never expect: the rear lens cap. It screws into the rear lens group, which unfortunately is also the thing that is the coma control. As for the front cap (which also screws in), you’ll probably leave that in the box with the hand-drawn spherical aberration measurements and the pretty hood. You’ll either use an MRC filter or a pinch cap to keep your fingers off the front glass.

Overall build quality. Done out in matte black chrome, the finish of the Sonnetar is a good match for a black Leica M-P or Monochrom typ 246. The black anodized finish is very tough, and the mounting ridges that you grasp to mount the lens will take bits of skin along with them. Numbers are clearly engraved and filled in white. They are legible and inoffensive. There is no way to 6-bit code this lens, since the rear flange is integral with the lens barrel (it is very much built like an old rangefinder lens with a rotating optical unit).

The glass (modified Sonnar design, more air-spaced) is perfectly clean and perfectly coated (from what I understand, MS Optical’s multicoating is a simple 2-layer). The reality is that the efficiency of modern coatings and the low element count makes internal flare a non-issue. Interior blacking is actually dark grey, which may seem puzzling, but if it’s good enough for telescopes, it’s probably good enough for camera lenses.

There are some build quality nits. One is that the lens (both on the sensor and in the rangefinder) hits infinity with about a mm of travel left in the focusing ring. This is probably an artifact of having that ring be the same part that provides the rangefinder cam. This might be of concern if you are trying to focus at infinity by feeling for a stop – and it is no different a problem than using an Asian LTM adapter that is a fraction of a millimeter too thin. It almost seems like you could just loosen the focusing ring screws and shift it so that infinity was on the stop

The other is that MS-Optical only uses a couple of actual lens mounts. The 51.6mm lens mount provides cam action that approximates a 51.6mm (Leica-spec) lens. Its frameline selection is determined by whether the mount is compressed around a notch in one of the bayonets or not. This lens uses about 90 degrees to go from 1m to ∞, which is quite short. This gives you a much faster acquisition time for focus but degrades the focus accuracy. Contrast this to 1950s and 1960s LTM lenses (and indeed the 75 Summilux), whose ponderously slow focusing rate can cause you to miss the moment completely. In any case, you are much better off using the ring than the lever because the larger diameter of the barrel provides better precision (because it takes more movement of the control surface per unit of focus change).

The $&@(!#% “coma adjuster.” The most famous feature of this lens is a “coma adjuster,” a ring around the rear element that has a white indicator dot and four distance dots (1m – white; 2m – white, 4m – red, and infinity-white). The lens is sold with an instruction sheet that tells you this is for adjusting “coma,” which would be the shape of point light sources (round or not). Why does anyone care about coma? It’s a big deal for telescopes, and that’s what Miyazaki designed for most of his life. What you get in terms of optical performance in the near range is a set of very subtle changes. Perhaps this operates better at a distance, but for its stated purpose, the adjuster seems a little bit gimmicky.

What is not so subtle is that the same control – determining the position of the rear lens group – has a tremendous effect on focus (because it changes the focal length of the lens) and on field curvature (whether the plane of focus is flat across the field or curved inward at the edges). This almost off-label use is actually very easy to exploit (see the discussion of what the directions actually say below).

Focal length control is very important on a super-speed lens. A Leica rangefinder assumes the same movement as a 51.6mm lens. Nominal “50mm” lenses that have a 51.6mm focal length can rely on simple movement of the lens cell when focusing to track from near to far at the correct rate. Shorter lenses (like 35mm lenses) have to translate a smaller amount of lens cell movement (front to back) to a relatively larger amount of rangefinder cam movement. Likewise, a 90mm lens needs the cell to move more than the cam moves. With most 50mm f/2 lenses, variances of a couple of 1/10s of a millimeter in actual focal length are not of great consequence because the lens has a little depth of field (or “fudge factor”). Lenses that have super-thin depth of field, such as an f/1.1 lens, require far more precision in their focal length to work well with a rangefinder. One can also surmise that the coma adjuster ring also serves as a calibration method for the lens that does not require reassembly.

According to the directions, this is how to use the coma adjuster ring:

Adjacent to the coma adjustment ring, you will find a white reference point (see the above illustration) to which an appropriate ring position has to be matched by rotating the ring. Using the coma adjustment system, a very high level tuning/focusing optimisation is made possible.

[…]

For Leica M Type Rangefinder Camera Users Initially, bring the red dot of the ring to the white reference point by rotating the coma adjustment ring. As you familiarise yourself to this lens, you may wish to change the ring position either to the left or right. For example, at the infinity best point, the actual focus point will be slightly brought forward (therefore, take a photo with focus point slightly backward). At the white dot that is best for 2m distance, a focus point will be slightly brought backward (therefore, take a photo with focus point slightly forward). This might take some practice and experience to achieve best results.

In real life, the tips for using this are:

  • Turning the adjuster toward longer distances will make the lens focus closer to the camera.
  • Turning the adjuster toward shorter distances will make the lens focus farther from the camera.
  • Putting the coma adjuster on 1m will cause a back focus of 15-20cm at 1m, which is not insignificant.
  • Putting the coma adjuster on ∞ will cause the lens not to focus (optically) to infinity.
  • Putting the adjuster about 2mm short of the 4m mark will produce best focus at f/1.1-1.6 from just under 1m to infinity. This is not surprising, since it is a distance of about 50 focal lengths (2.5m), which is a conventional distance at which lenses are tested. It is also apparently the setting used to measure MTF (as shown on the instruction sheet).
  • The lens will decouple from an M rangefinder at the minimum distance stop, so don’t do any testing below about 0.8m.

IN MOST CASES, YOU WILL ONLY BE MOVING THIS ADJUSTER 1 or 2MM FROM THE RED MARK. UNLESS YOU WANT TO GO CRAZY.

It really, really, really helps to have a LensAlign to calibrate the lens because you can see the zone of focus very correctly. Although you can trial-and-err it without this $80 plastic device, the problem is ascertaining the effect of focus shift. You want to hit a calibration where the zone of focus includes the intended point through as many apertures as you can – because like a lot of lenses in this speed class, the Sonnetar has under corrected spherical aberration that causes focus shift with aperture changes. The LensAlign lets you observe a band of high contrast as it moves (and expands) as you stop down. You don’t even need to shoot it head-on as you would with a DSLR; you need to check this from oblique angles too – because that is how you will focus your Leica in real life. Needless to say, if you are going to use this lens with a film camera, it helps to have a digital to get it dialed in.

Even within any calibration, the M viewfinder system (including the improved rangefinders for the M typ 240 and 246) has enough lash in it that the direction from which you focus – as well as small movements that don’t even produce a visible change in the RF alignment – can affect the focus point. So the word is “practice.” Wide-open, you will nudge to a slightly farther focused distance (without making the RF spot move).

Performance. All high-speed 50mm lenses (f>1.4) involve tradeoffs. The simple answer is that the Sonnetar has characteristics that vary depending on the coma adjuster setting, and these correspond pretty closely to the optimization differences in an Opton Sonnar, a 50/1.4 Nikkor LTM lens, and a 50/1.5 Canon LTM lens.

For most testing, I have kept the lens optimized at f/1.1 to 1/6 at distances up to 3m. It performs very well from 0.8 to 10m at f/1.1-1.6. If you get the calibration just right, you can keep it sharp through f/5.6, and it’s sharp across the field. At long distances, however, you get progressive blur toward the frame edges. This is gone at f/8. I suspect that the coma adjuster could overcome things, but distance shots are a little outside the use case for this lens (for distance, you are always better off with a slightly smaller aperture lens).

Sharpness seems to max out at f/1.6 (the dot between f/1.4 and f/2 on the focusing scale). Contrast is about double that at f/1.1. If something like the Canon 50mm f/1.2 LTM lens is your frame of reference, at wide-open settings, the Sonnetar is visibly better (and focuses far more accurately). If you are shooting at f/4 or smaller, something like the Canon provides much more balanced performance.

Here is a sequence that should show the differences at the wide apertures. If you click on the picture, you should be able to see it full-size. First, 0.8m, whole scene. Yes, the 44-year-old unopened bottle of Beam is real, as is the gaffe of keeping champagne at other than depressed temperatures. And no, I can’t explain the presence of the CFL bulb on the bar, since I own no fixture that takes them.

Next, check out the difference between f/1.1 (left) and f/1.6 (right) at 100%. The apertures shown in the metadata are computed by the M typ 246, so they are not entirely accurate. There is quite a bit of contrast jump in one stop.

Real-world, stressed out, trying to get enough distance to focus in almost complete darkness, you still get good results. This is f/1.6 at ISO 2500 and 1/12 of a second:

And this is the obligatory f/8 shot outdoors with a G filter.

L1000791

Flare is very well controlled except in extreme side-lighting, where you can get some bizarre effects. This is a characteristic of Sonnar-type lenses. There is some “glow,” which is the normal Sonnar flare on hard dark/light interfaces that occurs when the focus point is ahead of the object. It is more visible in the preview mode of an M camera than it is in the final files. Resistance to extreme backlighting is pretty good, a lot better than with the old Canon 50/1.2:

L1000799

Here is the difficult-to-replicate total flare failure mode. You might want to use a lens hood when the sun is in the corner. Or maybe not.

L1000790

Vignetting is not going to be a huge issue at close distances, since the barrel is extended. At f/2 and down, it is not obnoxious, especially when combined with the automatic corner correction on the M8/9/240/246. If you want to go very heavy duty on perfect corrections, use the Adobe Flat Field plugin for Lightroom. You will need to shoot baseline calibrations at the distances and apertures you normally shoot. You can do that after the fact.

Color rendition can be a little weird. The “tantalum” glass in this lens (probably standing in for less-exciting sounding “rare earth”) shows mild versions of the color enhancing effects of a didymium enhancing filter (like a B+W 491, Tiffen Enhancing Filter, or Hoya Redhancer). Magenta and yellow seem to be favored here. Here are some pictures that should illustrate this. For your evaluation of secondary characteristics, this is at f/2:

Chromatic aberration is a factor here but not in the traditional way. Wide-open, this lens tends to have the blur from adjoining colors bleed together. On an M typ 240, this looks a little bit like soft focus. On the M typ 246, this disappears completely, and the lens develops some killer contrast. This is characteristic of sticking a lot of old-school lenses on the new Monochrom body; a lot of older optical designs suddenly start looking awesome.

Bokeh is such a bourgeois concept. With spherical lenses, you either get universally good bokeh but bad focus shift (ZM C-Sonnar) or poor bokeh and reduced focus shift (50/1.4 Nikkor, 50/1.5 Canon). Unfortunately, with high-speed lenses, the latter combination (or in this case calibration) is much easier to live with. With the Sonnetar, you want to get as close to your subject as possible with as great a distance from it to the background as possible. Otherwise, you can enjoy what generation of Canon and Nikon Sonnar clones have experienced. By the way, here is a direct comparison between the bokeh of the 50/1.2 Canon and the Sonnetar. Maybe you can tell which is which?

L1001270 L1001341

Conclusion. If I did not currently own eleven 50mm lenses (just temporarily), I don’t know how I would feel about this one. That said, the Sonnetar is the one that seems to be welded onto my Monochrom. It’s quirky, it takes a lot of practice to use, and even after a couple of months of practice, there is still a lot to master. That said, it’s an elegant alternative to the Coke cans and second mortgages that tend to dominate the super-speed 50mm space.

The Leica Monochrom typ 246 and filters

20150712_115548

The Internet seems to offer very little actually useful information on the M typ 246’s response to color contrast filters. One would observe that this is a product of authors who have little understanding of color theory and the use of filters with traditional film materials. Let’s supplant all of these blind-leading-the-bind pages with a totally new, semi-ignorant page on the subject.

What do we know about filters? Or not?

The first thing to confront is that we don’t know as much about filters as we think we do. Part of the problem is expectations formed by reading filter pamphlets. These contain such questionably useful statements as:

Especially useful for clear contrast between blue sky with clouds and foreground. Provides a natural tonal rendition. Often used for subjects at intermediate distances. (Hoya Yellow K2)

…has a very pronounced effect and darkens violet and blue very strongly, green quite strongly, and even yellowish green a little. Landscape and architectural photos show an increased, almost “graphic” contrast, while a cloudy sky may already appear dramatic. Because the skin tones rendered by the filter color are noticeably lightened in comparison with plant greens, this filter is often used in nude photography outdoors to increase the contrast between the lighter body and the darker landscape. (B+W 040)

The only statement that is almost universally true in filter literature is that the 022/K2/#12 yellow provides a natural tone rendition. This is due to the fact that it makes blue darker than red.

But as far as contrast goes, the reality is that the effect of a filter is profoundly influenced by the color of the light hitting the scene – as well as the color of the objects in the scene. If the predominant light color is complementary to the filter color, then the scene will simply be muddy – because the filter acts as a neutral-density filter. Shoot a red filter in the mountains, and sometimes you don’t cut through the haze. Sometimes you create one.

Applying “standard” filter factors usually has a similarly disastrous effect. To make filters work, you absolutely have to start with a scene featuring colors that look different in real life. Depending on what you are doing, the actual correction may be far less than the factor implies. With TTL metering, you may have to decrease exposure to get what you want.

Depending on the vintage and construction of a lens, the use of filters can also cause focus shifts. Green filters can cause front focus with some lenses; red filters can cause back focus. These are accentuated on digital, where the imaging surface is much thinner than on conventional black-and-white films. This may be the focus (tehehe) of a future installment.

By experience, we can at least understand the following with the M typ 246: filters can have a very exaggerated effect, starting with yellow filters. The following from two months of testing and feeling this out:

  • A yellow-green filter (060, X0, Green 11) has small effects on exposure but puts more texture in people’s skin. Same as with film.
  • A green filter (061, X1, Green 13) has a noticeable effect on foliage. Same as with film.
  • The standard yellow (022, K2, Yellow 12) is still useful for correcting scenes to make color relationships work as expected. It actually makes a very good standard filter because it does not alter exposure much at all. It also has a noticeable effect on blue skies with the new Monochrom, much more so than on film.
  • The yellow-orange (023, G, Yellow 15) acts more like an orange (040, Orange 22). The picture at the top of this article was taken with a Hoya G, though you would think it was something stronger.
  • The deeper oranges (040, Orange 22) act like reds, and they are the practical limit of what you can use. Stop at 041. In daylight scenes, particularly in seaside settings with much blue light, these start to show diminishing marginal returns because they can affect most things in a scene.
  • Red is almost impossible to use.

This is somehow not surprising in light of the fact that Leica only offers filters in light green, yellow, and yellow-orange.

Testing M typ 246 with filters, by the numbers

Do these anecdotal observations have any real basis? The one way to find out is to move away from infinitely variable real-world scenes to see what the sensor does with white light. So here is a quick set of tests:

  • Sunlit and bright overcast conditions.
  • 90%+ reflectance target.
  • 90mm lens (M-Hexanon), defocused (lens at infinity; target closer than the lens’ close-focusing limit).
  • Manual exposure keyed so that white clips (the obvious limitation is that setting white to 255 might diminish slightly the differences between no filter and some filter).
  • Values are expressed as levels as measured in the center of the frame. This is to avoid having the results influenced by vignetting.
  • Blue line is bright overcast; red is direct sunlight. You won’t be using these filters in other conditions.

And the results with a whole pile of 46mm B+W filters is…

m246arith

Holy exposure cliff, Batman! Your stops are at 256, 128, 64, 32, 16, 8, 4, 2, and 1.

How do we translate this?

It is instructive to check out the B+W response charts that explain what we would expect to see (assuming, of course, a perfect sensing medium that could see all the way from UV to IR). Each filter does not make a perfect cut but rather has its own curve. Reds and yellows ramp up pretty quickly, and greens and blues are something of a free-for-all.

b+wcurves

What does Leica say about the M typ 246’s response?

Below is Leica’s own test data for the M typ 246 (I asked, and they sent it to me). The values are fairly consistent with the testing above using filters, taking into account:

  • This is chart still computed arithmetically.
  • Leica was no doubt able to run this more systematically, with a light source that could crank out much more narrow wavelengths than a filter would admit.
  • We don’t know at what stage in the imaging process these values are measured.

Regardless, Leica’s values are generally consistent with what you see mounting filters.

2015-07-27 M (Typ 246) spectral response

What real-world quirks should we expect?

There are a couple of strange things one might expect, and they were borne out by this test.

  • The 092 is labeled by B+W as 20-40x – on the M typ 246, it is more than 256x, meaning that the IR rejection of the camera is incredibly good.
  • The 081 (blue) has an unexpected spike in overall brightness. This cyan filter (used for B+W contrast reduction) also causes the camera’s metering system to overexpose (I was able to confirm this in testing).
  • The 060 (yellow-green) reads a little lower than Leica’s data on both Monochroms might suggest. This may be explained by peak camera response falling between the two filters (060 and 022) that simply wouldn’t show up on this chart.

Is it really different from the Monochrom Typ 230?

Now, in terms of the “rendering” between the M typ 246 and its predecessor, the Typ 230, we are told (anecdotally) that it is “different.” Is it? So let’s take the plot with real-world filters and convert it to log values (which for some reason fascinate the publishers of exposure data).

Note: every logarithmic chart has its own scale determined by the base; here, I used 255 (because that is how Photoshop reads out). Leica may have used a number based on raw output from the sensor. Kodak has a standardized negative density that informs its chart. The one thing that can be done with these charts is to compare shapes to see if the response goes up or down and where on the spectrum.

m246log

And then compare it to the M typ 230 chart for the original Monochrom (below), which is expressed the same way. You can see that these are not very different in shape – except that the Typ 246 seems to be a tiny bit more friendly to oranges and reds. It would actually be nice to get the raw data to plot these together, but alas…

M230log

This in turn can be compared to film. Note that neither Monochrom camera has the little blip in the red range that TX and TMY do. But that has a lot to do with the dark science of film design. One thing these charts do reveal is why you actually need to make sure that no UV light hits TMY – although the film is a little less sensitive to blue (and therefore needs less of a correction), it has quite a bit of UV sensitivity (consider a B+W 415 strong UV filter).

filmsensitivity

Upshot

All numerical silliness aside, the point here is that the responses of the Monochroms are fairly similar – and that on both, you should go easy on the strength of contrast filters – instead working to make sure you have a sufficiently varied scene to make their use meaningful.

Fuji X-T10, Time Magazine’s 35mm Camera, and Fuji’s direction

timelife

Unfrozen Cave-Man Design

The comparisons are inevitable (if you were born before, say, 1985). They are unnoticeable to Fujifilm’s obsequious band of pre-release “reviewers” (more on this later). But the similarity is undeniable. Fuji has, for its sixth camera based on the X-Trans II sensor and its eighth based on the 2011 Sony 16Mp base sensor, copied the design of a camera given away with magazine subscriptions. Hopefully unconsciously. That said, let’s not denigrate the Time-Life unit too much; it has a 50mm f/5.6 glass meniscus lens that at a small enough aperture will be competitive with multi-element lenses. It also contains so much lead in a ballast plate in the base that the scrap metal content outweighs (literally) the purchase price. Operators are standing by.

The only thing that makes the X-T10’s design really egregious coming from Fuji is that the Fuji X line is supposed to be a better-thought-out alternative to DSLRs. Yet here we are, in 2015, and the most recent two models have aped DSLR designs. Are we as a market that gullible? Do they think this will somehow make it easier for us to swallow giving up heavy SLR gear? Whatever it is, it does not say good things about the market or the manufacturer.

The silly game of making one thing look like another goes back a while. Consider the Horsey Horseless Carriage. Whether it was serious or a parody perpetrated by a rich gentleman, you get the point:

horsey

One is left to wonder whether the head was to be sourced from taxidermy or upholstery, but whatever the intent, it was not going to end well for horses.

Mimicry in camera design is not new, but it is a relatively recent phenomenon. In most cameras, form has to follow function; a camera is a box with a lens on one end and an imaging surface (film or digital) on the other. In the old days, there were no twin-lens reflexes that looked like rangefinders and no SLRs that looked like anything else. It is probably also fair to say that with a few exceptions (like the Zeiss Tenax or a couple of Raymond Loewy specials), no one actually cared whether a camera was ugly or not. After all, a Rolleiflex is only attractive in the context of twin-lens reflexes. You wouldn’t put it on a coffee table.

For some time, the proportions of digital SLRs were tied in to the film cameras that spawned them. Some of this was understandable; makers were in many cases recycling the chassis castings/moldings of existing cameras – or reusing key components like mirror/shutter boxes and viewfinder assemblies. When DSLRs started to feature their own purpose-built main castings, there was some carryover that were hard to explain – such as why grip surfaces retained proportions originally designed to house 35mm cartridges. But then again, the Space Shuttle’s engines’ dimensions are ultimately traceable to the size of the rump of a Roman soldier’s horse.

Fuji, for its part, stuck to function in designing its early X-series cameras. The X100 looked like a baby Leica M3, but any combination of an integrated optical finder is going to force a certain layout – the window either goes on the left of the right of the lens, and most people are right-eye-dominant. Yes, there was a little window-frame embellishment, but that has evaporated in the X100T. The X-Pro1 carried very subtle call-backs to the G/GL690-series cameras, but it too stuck to the function-defines-form script for the most part (it is clear given subsequent cameras that Fuji made this camera much thicker than it needed to be, given that it had a non-articulating screen). The XE, XM, and XA cameras looked like other finder-equipped or finder-less bodies – various Panasonic G, Sony NEX, and Olympus EP cameras.

The industry turning point (for the worse) came with the Olympus OMD-E5 in 2012, an unabashed visual clone of any of a number of Olympus OM-series SLRs. There was no reason to stick a pentaprism-looking housing atop a mirrorless camera. Pentax was also right there with its K-3. As if it had passed through a mirrorless camera development stage, the K-1’s top bump suddenly blossomed into a full-figured faux prism.

Fuji was always late to the party, and it took Fuji until 2014 to imitate SLR design in the X-T1, the pretext being that the big EVF required a pentaprism “hump.” Fuji dropped that pretext with the 2015 release of the blocky X-T10, stating now that it did this to recall Fuji’s (forgettable) AX line of SLRs. But the X-T10 does not look like an AX at all; it looks like a rinky-dink plastic camera. And its design appears driven neither by function nor aesthetics. It’s an ugly little box.

Why should anyone care?

On one hand, one would be tempted to ask, who cares? Fuji owners (and potential Fuji owners) should. Like a photographic version of roles written for Jason Statham, Fuji has for three years pumped out camera after camera based on the same sensor and incremental inclusions of off-the-shelf technology. Fuji’s three big additions since the X-Pro1 – namely, high-quality EVF technology, on-chip phase-detect focus, and face-detection – were set up for consumer products before the X-Pro1 came out (check out the timing of the NEX-5R and its patents). By the time the X-E2 came out, all the pieces were in place for a serious update to the X-Pro, the “flagship” camera. Between then and now, Fuji has instead pumped millions into design, tooling, and software for multiple minimally differentiated cameras – far more than it would have taken to put an X-Trans II chip, EXR II processor, and better EVF into an X-Pro2. This points to one of two possibilities: (1) the X-Pro1 was such a dog for sales that management required the engineering team to start doing what other mirrorless makers were doing or (2) Fuji has turned to avidly churning the market to keep up market share in the declining interchangeable-lens market, and an updated X-Pro1 was not anticipated to do the job.

1. Looking like what sells. On the first point, it is of some note that the X-E2 resembled the Olympus and Panasonic Micro 4:3 cameras, as well as the Sony NEX-6 and -7 APS-C Cameras. The X-T1 and -T10 have followed other manufacturers’ quasi-SLR digital designs. The lens selection in compacts of both formats (APS-C and M43) also reflects a more into competing with entry-level DSLRs: zooms, big zooms, and big primes.

This direction (physical bloating) undermines what APS-C (and Micro 4:3) were supposed to be about: smaller, lighter cameras. This has never really happened: Fuji’s and others’ lenses are not as much smaller than FX lenses as one might have been led to believe. Part of this may be that it’s cheaper to design big telecentric lenses than smaller, more symmetrical ones that require offset micro lenses. And autofocus probably exerts its own size expansion.

But for people who liked the idea of the X-Pro1, this translates into a camera that is somehow bulkier than a 24x36mm Leica M. That does not seem to be the right direction in an era where camera phones (that everyone is already carrying) are eating into compact camera sales. If aside from a camera phone, we are going to haul around another box with its own lithium-ion battery, one that is not plugged directly into social networking, do we want it to be bulky?

2. Churning and burning. The second possibility is more sinister-sounding – but it is supportable. Fuji’s product releases have occurred twice yearly since the X-Pro1. That is very often considering that the underlying technology has moved very little since fall 2013. Fuji’s marketing strategy for the XF has been simple: use shills to build up excitement, release products at high prices, slash prices when sales start to flag a couple months in, and then build excitement for the next big thing.

Fuji is not alone here, but it seems more visible in its use of “reviewers” to promote the process. The practice began with with some Fuji employees — but at least they disclosed who they worked for. But then it moved on to “reviews” started coming rom (a) semi-pros; (b) Fuji-sponsored photographers; and (c) a few easy marks who believe that whatever just came out – from whatever manufacturer – is the greatest thing ever (we all know who they are). Throw into the mix some hyperventilating Fuji-oriented sites that get revenue when people click through to retailers, and you get the perfect storm of non-objective reporting. After all, whether it trips FTC guidelines or not, who would bite the hand that feeds him? And in a world where people pay good money for SEO work, catapulting your photo business to the top of any search has value.

Then comes the product. It’s great. It takes great pictures. I know this first-hand.

And a few months later comes the burn. Left with a run that it can’t sell, and even absent any fundamental spec change or replacement model, Fuji will usually slash prices 20-30% within six months. This gives an impression that every Fuji model is overpriced to begin with – and in slashing new prices, Fuji puts its own new sales directly in competition with the secondary market. This in turn hurts middle-class amateurs trying to unload old Fuji equipment to upgrade within the line. This is a great strategy for fixing a one-time inventory problem, and certainly no budget shopper in the used market will object. But especially where forced depreciation occurs without some compelling improvement (or even the oddly missing “camera body” roadmap), existing users start to feel burned, and smart shoppers learn to hang back. Why would you ever buy new? Look at completed sale prices on Ebay. Buying an XF body or lens new costs you 30-40% the day you open it. Put another way, Fuji’s pricing practices violate a fundamental rule of luxury goods sales (and let’s face it, a $1,300 camera body is a luxury good for most people): never slash MSRPs. You can have occasional rebates, bundles, or “demo” units. But once you start slashing prices, you begin degrading your brand equity. Or has that happened already?

3. Rewarding risk? Fuji should never lose track of the risks that one takes on a proprietary camera system. XF lenses do not fit anything else. There is no repurposing the same lenses on old film bodies (such as with Canon, Nikon, Pentax, and Leica) – or even repurposing them on different types of digital bodies (you can stick the same Nikkor on an APS-C D7500, FX D4, and 36Mp D810, for example). In a closed digital system. people invest in a collection of lenses in part on the premise that the line is going to continue – and that the line will remain viable compared to other systems. In a sense, everyone knows that they will be replacing camera bodies in 3-4 years. But when real upgrades never come, it causes justifiable questioning. And it’s not just sensor resolution. It goes to functionality:

  • Will battery life ever improve?
  • Will there ever be a good TTL flash?
  • Is there something about X-Trans decoding that makes it too processor-intensive for a 24Mp sensor?
  • Is the “organic sensor” thing a dodge for never upgrading the X-Pro?
  • Will the video function get less “aliasy?”

These are questions that Fuji should be in a position to answer.

Now what?

Fuji presents a strange case. Its X100 line is fantastic (and its marketing low-key).
