Fuji’s X-series aperture rings?!

I was trying to finish a writeup on the Sony A7r2 with a 35mm lens versus Fujifilm X100-series cameras and got off on this tangent, which became too much of a distraction to appear in the other article. Sorry to drag you along for this ride, but it’s a gloomy, rainy Saturday afternoon, and it was either finish this or develop 12 rolls of film…
Someday, when Fuji is put in a room with bright lights and given the leather-glove treatment, it might be able to answer the question of why X-series lens aperture controls turn right toward their smallest apertures (or A). Although this sounds like a trivial problem, this kind of thing can and does cause momentary confusion when you are using two kinds of cameras at the same time. I discovered this over time when an X100T was one camera in use and a Leica M was the other. I’d end up with a little bit of confusion in aperture priority momentarily. The most frequent error was cranking the Fuji lens to A instead of to 2.0. Not a huge problem in terms of getting some shot — but perhaps a problem in getting the shot I actually wanted.
The way controls work is actually a big point of study, and the stakes with cameras are quite low. The stakes can be quite high in other contexts like aviation. Most of us encounter mild annoyances like badly-designed remote controls, Apple Watches, and manual transmissions that have reverse in a bunch of different inconsistent locations. Luckily, a digital camera is not an airliner, but you get the point. And the more tired someone is, or the more stress he or she is under, the more likely there is going to a problem. And photography can become stressful.
The point that was going into the other article is that “any manual control system that has sufficiently annoying quirks will encourage the use of automatic systems to avoid it.” If you take issue with that, consider how little you have actually used manual focus on AF-capable Fuji XF lenses. Their focus direction might have been a problematic issue as well, but frankly, the focus-by-wire is so terrible that everyone just uses the superb autofocus.
Digital camera viewfinders are pretty poor examples of human-machine interfaces. They are cluttered, they show numbers as digits and not graphically, and and there are too many things going on. This is a fault of pretty much every digital camera (except for Leicas, whose viewfinders have 8-segment LED displays that convey virtually no information).
One major point of the X series is to present tactile controls. The X-series aperture ring, both on the fixed-lens camera and interchangeable XF lenses, is a control-by-wire actuator that could have been designed to work in either direction. Perhaps more remarkably, it was designed both opposite to the Leica rangefinders the X-100 cameras and X-Pro cameras visually mimic and also opposite to about 60 years of Fuji’s own rangefinders.
This is not the first time an “Opposite Day” has happened; in 1998, Leica reversed the direction of the M film camera’s shutter speed dial for the M6TTL, and people went out of their minds. The problem was that on a Leica, LED over- and under-exposure arrows previously told you which way to turn the shutter speed dial or the aperture ring.* They were now inaccurate as to the shutter speed dial. With the M7 and then the digital M8, M9, M240/246/262, and M10 people just put the dial on A and left it.
*By the way, Leicas only had acquired LED meter indicators in 1984 with the M6, so people only had 14 years to have their brains calcify around the way the meter was supposed to work with the LED indicators. Previous Leicas, laying aside the M5 and CL, had no meters at all.
Back to the story. Now which systems turn right toward minimum aperture, like the X100n and the X-series mirrorless cameras? Rangefinder systems are color-coded red and Fuji’s own rangefinder systems bold and red.
- Fuji’s X series 35mm SLRs
- Nikon F lenses (historic ones)
- Canon FD
- Pentax K
- Pentax 6×7 SLRs
- Bronica RF645 rangefinder
- Canonet rangefinders
- Contax/Nikon rangfinders (not produced since the 1960s)
Which systems turn left? This is a start:
- Leica screwmount (including clones by Avenon/Kobalux, Canon, Konica, Minolta, Voigtlander)
- Leica M lenses (including Minolta M-Rokkor, Konica M-Hexanon, and Voigtlander VM)
- Fuji V2 35mm compact rangefinder
- Fuji 6×7 and 6×9 interchangeable lens rangefinders
- Fuji GW and GSW series 6×7, 6×8, and 6×9 rangefinders
- Fuji GS645S and GS645W rangefinders
- Fuji GW670 rangefinder
- Fuji TX / Hasselblad X-Pan
- Contax T rangefinder
- Contax G compact interchangeable-lens camers
- Mamiya 6 and 7
- Minolta Hi-Matic
- Plaubel Makina 67
- Fuji GX680 SLR (if the lever could be equated to a ring)
- Copal and Seiko medium-format shutters (same note) (and Fuji G617/GX617)
- Rollei 35/35s
- Olympus Pen
- Leica SLRs
- Minolta SLRs
- Konica SLRs
- Olympus OM SLRs
- Contax SLRs
Talk about being on the wrong side of history… The vast weight of rangefinders over history, particularly the ones the X series was intended to evoke… went the other way. What is inexplicable in this is that the X100 and XF-mount cameras were clearly very carefully designed from an aesthetic and basic control layout perspective. For reasons probably known only to one or two engineers, Fuji took a flier on this one. Was the idea to bring back the glory days of a Fuji 35mm SLR system that the world had forgotten? Left-handed designer? Conscious counterculture?
It is difficult to believe this was an oversight. But it’s also difficult to divine why it would have happened.
Vapid vainglorious video

This site would have no pictures if I could get away with it. The predecessor site had few. Still photography is a visual art whose technical aspects generally can expressed with words or static pictures and diagrams. Unless you are illiterate or incapable of abstract thought, you do not need a video to show you how to turn a shutter speed dial, how to take a meter reading, or how to agitate film in a developing tank.
One beauty of the human mind is learning by theory, maintaining knowledge in the abstract, and then executing it in practice. You can see the words “invert three times every 30 seconds” and figure out what they mean in seconds, not minutes. When you think about the technical side, there is little (if anything) that calls for video. In fact, unless you have a video-graphic memory, you may have to take notes on what you see — which means you could have started with a written description in the first place.
By the way, the answer is 7 minutes at 20º C for almost any normal black-and-white film, in any normal developer.
The artistic or expressive element, likewise, can be expressed or exemplified with still photos. When you think about it, the power of images is such that when you pick up a coffee table book or look at a photo site, you might never read the words. There is a maxim in literature that poets should not interpret their own work. That probably goes double for photographers describing or even creatively titling their own images. We’ve all seen it, the photo of a pasty-skinned, depilated nude model (male, female, take your pick) in the middle of Death Valley, or among prickly pears, with a title like Natural Beauty. Bill Mortensen did a great job skewering this and every other trite figurative subject, back in the 1940s. In books.
Everyone seemed to get along fine with websites (and before that, magazines) that summed up photo products in one page. Here’s that super dorky Pentax, here is what its lens does, here is a non-damning conclusion from a site/magazine that needs Pentax advertising.
Something that never ceases to amaze (or horrify) is number of Youtube videos about still photography and its apparatus, particularly film photography. This might prove that there is something worse than the Hollywood-movie-about-making-Hollywood-movies. Maybe video-about-film-photography doesn’t have the same potential for creating a navel-gazing singularity. Not quite the same potential. But close.
Overestimating how cool you are
Many people who make Youtube videos about still photography and still photography equipment vastly overestimate how much people want to see them (and by “them,” I would include myself).
Or see their monster jellybean Golden Sherpa® table microphones. This was not a good look on Larry King, and was not a good look on anyone. Also, Larry King was not a good look on anyone. Not even on Larry King.
Or check out their stylish walking around, contemplating… stuff while wearing messenger bags. Sir, we all know that’s a camera bag and that it will crush the life out of even the most carefully basted sportcoat shoulders. A gentleman would never carry anything larger and cruder than a Contax T, which slips handily into the pocket of any pocket of any piece of clothing.
Or endure the name-checks. Many of these videos look like unpaid promotions for purveyors of peripheral photographic gear. On some videos, you can ascertain that every manufactured good in the scene has a name and a manufacturer. Please, do tell where I can buy another $70 nylon strap that looks like something cut out of the restraint system of a passenger car.
Or to listen to weird smooth jazz music in videos that have no words. Somewhere it’s popular to unbox cameras wearing white cotton gloves while something approximating Kenny G plays in the background. Well, at least it’s not as creepy as the videos with synthesized robot voices.
Some presenters are attractive and well-spoken. Some are not. This is not to say that having super-attractive people do these videos would be much better (pointing away from their faces and perfect hair/makeup: “the camera is down there”).
You have to calibrate the aesthetics-to-content correctly. Back in the 1980s and 1990s, when they made color books about doing photography, you got 90 pages of correct but basic instructions and 10 pages of photographs, of which one or two images usually was (were) soft-focus semi-nude shots that revealed some previously-undiscovered British paraphilia. The one that springs to mind was the topless woman wearing a construction helmet and safety vest, holding a stop sign. I think it was hidden in a book about light meters. Not even years of therapy can counteract seeing that. Fortunately, Youtube has age/content gates that prevent equivalent video education from propagating the Road Repair Crew fetish/lifestyle.
Also, it is very selfish to ask others to judge you by posting videos of yourself all the time. People have things to do! It is not your audience’s privilege to have to slavishly critique you every time you spam a Facebook photography group with your latest and greatest. Many in your audience accept keeping people away from deficient videos as their duty to society. It’s a form of noblesse oblige exercised by those who have free time (or at least pretend to while not stuffing Amazon trucks). And do you know what happens to the nasal passages when someone laughs and snorts while drinking tea? Man, think of the innocent viewers!
Is your video a Wonderbra?
A lot of videos suffer the vice of promising a lot while hiding disappointing content. Many things in the clothing world do this for women’s and men’s bodies, pushing, pulling, compressing, or expanding the body in various ways for the purpose of selling. Car makers in Detroit got busted by the Federal Trade Commission for building 8×10 cameras with curved backs that made huge 1960s and 1970s cars look even huger. Food manufacturers had to explain that the graham cracker was not really six inches square like on the front of the box.
The lack of information density is not just a feature of photography videos; it is also feature of almost any technical video about anything. If the solution for cleaning something is vinegar or ammonia or something else, there is no need to package a very simple idea in a very elaborate video. If the key thing in touching up car paint is selective 3000-grit sanding and progressive application of thin layers of paint with more wet sanding, well, that’s easy to say. Omegas are almost as good as Rolexes. An Acura is not as fly as a Bentley. Follow me for more recipes.
Did you ever wonder why people take at least eight minutes to convey only the smallest piece of information? It’s because the shortest video on Youtube that supports ‘midroll’ advertising. Padding is also encouraged by the Youtube minima for watch hours (4,000) and number of subscribers (1,000). This should tell you everything you need to know about why most videos come with click-baity titles but are then letdowns – and you rarely come out of watching one feeling like you’ve learned something. It might also explain why people plaster social media with links to their videos. You are a means to an end. Just not yours. Like this video I was watching the other night, “Ten things you didn’t know about sprocket layout on Kodak 135 films. The last one will break your heart.”
Curation, curation, curation
But isn’t the real issue here curation, or the concept that something should filter out the fluff? One of the biggest differences between the pre-internet media and now is that there was a considerable cost to creating and propagating content. And particularly for print, editors (note, not Redditors) and publishers made decisions about what would be salable. They bore the risk of failure. It was not easy to expose the public to unadulterated garbage; works had to pass some basic test of economic viability. Self-publishing was seen as sleazy.
Not so much is it so in the Youtube model. There, uncompensated individuals use personally-funded (and cheap by historic standards) video equipment to produce their own videos, where they are allowed to post them, with no advances and in many cases zero long-term compensation. And no filters.
The video site uses to the content to earn advertising money – and then kicks a percentage of that down to users. The per-click and per-engagement pay is small – and it is difficult to justify the time investment in terms of money. This causes many content purveyors to turn to prostitution affiliate relationships and accepting free loans of equipment. How long do you think a manufacturer would keep sending you things to review if you kept trashing them?
This creates a morass of content of varying quality that is difficult to filter. People are trying like crazy to be seen because being seen might mean making money. People are trying like crazy to see something useful. Guess who wins? Neither of these two groups. Someone else, though.
Some video content on photography is really, really good.* If you read all the way through this, you know this had to be said. But if a diamond is mixed in with too much debris, it creates a certain fatigue. And that is the point, in too many words, of the twenty-five minutes lost in writing all of this (ok, plus another 7 minutes on a patent site and then 5 minutes deciding that even the 1940s patent description of squeeze-and-lift was unsuitable for this site).
*Steve Meltzer’s (lkanagas) video parody review of the Leica Monochrom is hilarious, including a camera slip that reveals that a revolver was one of the things he unpacked from the factory box.
Funleader 18mm f/8 Caplens M-Mount

I’ve always thought of myself as a fun follower, not a fun leader. Well, someone had to try it, right? Two weeks and $179 later, I got a small package from China via City of Industry, California. I almost threw away the lens by mistake. The following will be a brief initial review of yet another interesting lens from China’s burgeoning camera lens industry (another example is the Venus Laowa 15mm f/4.5 shift, reviewed previously).
Funleader is a somewhat obscure company. I actually saw the lens on a targeted Facebook post, making that pervasive surveillance useful to me for the first time ever. The company makes two versions of the Caplens and a drop-in conversion mount to put the 35 Contax G Planar on Leica M bodies. Everything appears to be designed by Mr. Ding (who is the counterpart of Venus’ Mr. Li).
The Funleader 18mm f/8 cap lens / Caplens / whatever is a follow-on to the company’s original 6-element ultrawide-in-a-cap. The difference for Leica M mount is that the lens can actually focus, which is a big deal because f/8 is not quite pan focus for an 18mm lens. The focusing mechanism on the lens is a little lever with a rotating cell. The focusing scale is marked 0.45m, 0.7m, 1m (with a click), 2m, and ∞. This lens is designed for Leica M mount, though in a future installment, I will plug it into a Sony A7r II and a6300 just to see what it does with those.
My assessment of this lens is that it is shockingly not bad. It’s pretty clear that this takes a direct shot at the MS-Optical Perar series of lenses costing five to six times as much (depending on what fetishized finish the Perar features). You’re not expecting the Funleader to compete with a ZM 4/18mm Biogon (which is still five times the price and ten times the thickness…). Let’s do the quick run-through.
Construction. The lens is solid aluminum, decently finished. Mechanical action is nice. All markings are engraved, or at least etched through the anodized finish. This includes the obnoxiously large “FUNLEADER” logo, but a little Sharpie marker will make that less visible. The lens comes with a rear lens cap, but it’s somewhat puzzling that there is no front cap (it would take a 36mm push on, notched for the focus lever). There are no filter threads. The lens weighs 40g, or about 1.3 ounces. It’s not much bigger than a body cap, hence, “cap lens.”
Focus. The lens is not rangefinder-coupled, though the mount will cause the camera rangefinder to read a little over 2m. If you can validate the correct focus-lever position on the lens so that the optical focus matches the RF, you will have at least one place where you can precisely focus. To do this, you need to use LiveView or an EVF. The 1m click stop on the lens is good for moderately close objects. But if you really want to be precise, you will crank it to ∞ outdoors and use an EVF indoors. Or focus-bracket. The Leica M EVFs can easily work with lenses at t/16, so this is no challenge. What might be a challenge is that indoors, you will be on a high-ISO marathon and that focus peaking may require some judgment calls. Fortunately none of those calls are difficult.
Aperture. The iris changes quickly and easily from f/8 to f/8 to f/8 and then back to f/8.
Sharpness. As noted, focus does make a difference, and it seems from looking at prior tests that the original Funleader Caplens (fixed focus) did not have a small enough aperture to cover all distances. Although the caplens is not critically sharp on infinite subjects (like a lot of wides, you are actually best advised to shoot close-to-mid distances), it does have enough bite to work. The following two pictures are scaled down to 3000×2000, but they will go large enough to see that the lens is actually more than passable. In fact, it’s embarrassingly good in some ways (but read on). There is little or no “smearing” at the edges, but where that appears in other Leica-mount lenses, it disappears by about f/8 anyway.
Near (M typ 240):

Far (Monochrom Typ 246)

Casual tests reveal sharpness consistent with at least the 10lp/mm metric shown for the lens if not also 30lp/mm.
Distortion. There is actually vanishingly little distortion at 1m and on. No sample picture is distortion corrected, or even cropped. This is not a symmetrical lens, at least not obviously, but it does have the same straight lines. Distortion is spherical, from the looks of it.
Falloff. Ok, there is tons and tons and tons of falloff on this little guy. Corners are 1-2/3 stops darker than the center. The M typ 240 metadata generator says variously that the exposures are f/8 or f/11 overall. M cameras compare on-sensor exposure with a small photocell eye. The measurement is not perfect, but it can often be very close.
Color shifts (Leica M cameras). This one suffers from the modified bandiera italiana effect, shifting substantially purple on one side and bluish-green on the other. The exact left-right balance seems to depend a bit on the angle between the light source and the lens. The color-shift effect is an artifact of Bayer sensors, complicated sometimes by the microlenses on Leica sensors. You knew that was coming. But it’s an issue on many lenses, particularly symmetrical wide-angle lenses. The “center” can be manipulated slightly by pushing the lens hard from side to side. On some M cameras, there is just enough tolerance to shift the lens on the camera bayonet slightly (the lens flange is slightly smaller than an M body mounting flange).
The color-shift effect should be correctible using Adobe Flat Field. If you even care enough to worry about it.
The Leica Monochrom cameras could care less. They are colorblind anyway. The color shift actually helps darken skies in b/w landscape shots (the picture above was actually taken in bright overcast).
These color shifts should not be as pronounced with film cameras, but film cameras would likely yield poorer sharpness due to the inability to check focus.

Performance on Sony A7R2. Since the optical part of this lens was originally developed for mirrorless cameras, it is not much of a surprise that it performs well with them. Some notes:
- The A7R2 viewfinder is capable of displaying images from f/8 lenses with no problem.
- It is a bit easier to focus with the A7R2 focus peaking than with the M cameras.
- The image stabilization function makes up for the slow maximum aperture. Image stabilization does not fix moving subjects.
- Sharpness is good across the frame. Focus looks correct with a Novoflex ($$$) M to Sony E adapter, and infinity focus may be affected if you use cheaper adapters that are “thinner.”
- Color-shift problems are fairly neglible. Vignetting is still there. The vignetting looks symmetrical, but the color shift makes it look a little lopsided.
Spring Blossoms Yes, the fabric blinds are grey, not purple. Try to keep your camera strap out of the quasi-dashcam picture.

Room for improvement. Funleader, if you are reading this, here are a couple of things that would make this lens more fun. These are not critical, but they would improve the user experience a bit.
- A front lens cap, rubber. This lens makes a camera pocketable, so why not protect the glass from the things people carry in their pockets?
- Depth of field marks (this would just need to be two tick marks on the rotating part of the lens).
- 6-bit coding (achievable through simple engraving of the back on the black version).
- An Adobe Lightroom correction profile.
- Wider flange. The lens flange is not quite as wide as an M-camera’s bayonet mount. It would be helpful to have more of a grip surface for mounting/unmounting, since Leica M cameras have very stiff bayonet springs.
- Some way to mount filters – magnetic ring on the front?
- Optional f/16, f/22, and f/64 Waterhouse disks to drop over the lens. When shooting in bright sunlight, it makes sense to stop down. It’s probably not practical to put an iris in a lens this small.
Initial Conclusion. The Caplens is an interesting and creative democratization of the MS-Optical Perar line of lenses, not so fast but a lot cheaper. The performance is surprisingly good, especially given the number of pans of the prior version in reviews. It’s not a 4/18mm ZM Distagon, and in color, it has some Lomo-ish (or 4,5/21 ZM Biogon) characteristics, but all in all, it’s a very nice lens for the money.
