End-stage Nikon manual focus
There must have once been an awkward moment when Homo sapiens neanderthalensis saw a gangly baby Homo sapiens sapiens and wondered, for the first time, what the future would be like. The Neanderthals basically merged into the surviving human line (or were eaten — the explanation seems to vary now) — and essentially disappeared. But not before giving Europeans those nettlesome brow ridges and occipital buns.
Neanderthal shock happened sooner in the Canon world than it did for Nikon. Canon released its last mainline* manual-focus camera (the T90) in 1986. Canon did not then engage in a merging of genes but instead a lens-mount genocide. FD lenses faded fast as EOS came to rule the jungle. Nikon took a few more years to get there in 1990 with its last manual focus camera, though that camera lingered for five years on the market — and Nikon never really gave up on the F-mount. Well, not immediately. Like Neanderthals, some degree of interbreeding was available, but all that fur began to repel people after a while. All of this was 23 years ago now.
By the way, when the last newly designed Nikon MF SLR went out of production, this was dominating the disco:
Nikon would in 2001 release the FM3a, but like the contemporaneous Beatles 1 album. It was just a rehashed FE2 with a new shutter. And that was so long ago that kids born then are old enough to vote. If you were an adult excited about the release of the FM3a, you’ve probably just passed out of the “18-35” demographic, if not past the “uncool 44” milestone. But don’t worry – Nikon has your back with retro-rerun cameras like that, the S3 and SP. Because it’s more fun to reminisce with cameras that were shiny and new (the first time) before you were born.
* By mainline, I mean serious and mass-produced. Yes, Canon made a craptastic T60 and Nikon made (or branded…) the FM10, but these were cameras for developing markets or students.
Detour into how Nikon’s product strategy: so many cameras
It would not be a Machine Planet article without a detour into some kind of editorial, and here is one: digital cameras did not usher in the age of meaningless upgrades and gimmicks designed to excite camera buyers into “one more body.” Film SLRs were the greatest feature-chase of them all: the lenses and the film are the ultimate determinants of performance on a film camera; everything else is metering, motor, and in some cases autofocus.
Consider that in 1980-1985, Nikon fielded five prosumer cameras based on the same platform (FM, FE, FM2, FE2, and FA), at the same time it fielded three based on an intermediate architecture (EM, FG, and FG-20), and a next-generation intermediate (N2000/F-501). All of these variations revolve around binary features/exclusions: needle meter or not; matrix metering or not; internal motor or not; program mode or not. And you thought Sony had a short attention span?
To be fair (why start now?!), by the sunset of Nikon’s manual focus cameras in 1995, post-processing was out of the reach of most people. Photoshop was at version 3 and barely able to handle the tasks it routinely handles today (it also fit on 5 Mac floppies…); scanners were insanely expensive; and if you had a bad slide, you were out of luck. If you had a bad negative, you were mostly at the mercy of Candice at Fox Photo to maybe run that one neg through the Fujitsu at N-N-N-3 instead of N-N-N-N (this person actually existed, was roughly my age, and was quite cute).
Even when Nikon made the jump to autofocus, this proliferation continued, with performance carefully meted out between models that used the same AF module (consider that the N50, N70, N4004, N5005, N6006, N8008/s, and F4 used the same module – with outcomes so different, you have to wonder what they were holding back.
But what was going on with the lenses?
Nikon’s lenses had a more tortured history that got off to its first wrong turn when Nikon started releasing metered prisms. That would have been the time to revise the mount to include aperture information (relative and maximum). Almost the entire subsequent drama of Nikon lenses was a product of trying to fix that: prongs, AI, AI-s, CPUs. When the Photomic metered prism came out in 1962, Nikon already knew that it was enough of a market force that it could have moved to a meter coupling in the body without losing its user base. For six long years, Nikon’s meter prisms required the user to set the maximum aperture of the lens on the meter, manually.
Actually, that didn’t just stop in six years. In 1968, Nikon introduced the FTn finder, with its semi-automatic indexing: mount the lens; turn the ring right, turn the ring left, done. The kludginess of this solution was only more glaring when companies like Konica were releasing lenses that could transmit maximum aperture information with a pin on the back of the lens (as opposed to a poky thing screwed onto its aperture ring) and using irises that were consistently linear, so as to allow automatic control of the iris. Granted, shutter priority did not predominate as a single-factor autoexposure method, but the point was that Nikon was well behind the curve. By 1971, Canon’s pro bodies had moved the meter cell to inside the body and were transmitting relative aperture position invisibly.
Nikon’s Aperture-Indexing (AI) lenses did away in 1977 with the prong, song, and dance because they fit cameras that only needed to know how many stops the selected aperture was away from wide-open. If anyone knew what the max aperture of the lens was, it was the user – not the camera. AI was in a way a step backward from the FTN, since it was only a system for transmitting relative apertures. And AI-only bodies turned out to be the full-employment act for repair people and machinists – because mounting an old lens on an AI body, absent modifications to the lens, the mildest of which was a new aperture control ring, would cause damage. AI ushered in a tiny doubled aperture scale, the Aperture Direct Readout (ADR) that some cameras could display in their viewfinders via a wedge prism, like the F2AS, F3, FA, F4, and F5.
The next iteration, AI-s (1981) brought Nikon almost up to date. It finally added a maximum aperture indexing pin to lenses (as well as a pin that transmitted the focal length to the camera. The only camera to fully implement this scheme was the FA, for its program and shutter-priority modes. There were three implementations of AI-s:
- The FA used the full AI-s protocol for AI-s lenses, going open loop when shooting AI-s lenses (because it knew the maximum aperture, focal length range, and stop-down rate) and selected a program based on focal length. It went closed-loop when shooting AI and AI-converted lenses. By “closed loop,” I mean the camera reads the scene, stops down, takes another reading, and finally fires.
- The FG and its replacement the N2000/F-301 all used a similar open/closed-loop setup, except these cameras could not read the focal length via the pin and thus only used one program (or one selected by the user)
- The N2020/F-501 would act like an N2000/F-501, but it could switch to P-Hi from P-Auto when a CPU-equipped lens with a longer focal length was mounted.
Of course, with closed-loop exposure, the only value of AI-s is purely informational; the FA and FG/N2000 systems don’t really need to know maximum aperture to work. And when it comes to “Program” operation for AI lenses, is it really programmed in the sense of a neat little graph – or is it shutter speeds programmed against apertures stopped down against the maximum?
A tale of two cameras
Nikon’s technological peak came with the FA, pretty much the most sophisticated camera anyone had ever seen. Four (count ’em!) exposure modes – Program, Aperture, Shutter, and Manual, all powered by two MS-76 cells. Matrix metering with any native AI lens. Program shooting with any AI-s lens. LCD display in the viewfinder. And… it wasn’t quite ready for prime-time, developing a reputation for having flaky electronics and poor matrix metering. Or so people say.
In 1990, the successor to the FA, the N6000, hit the scene. The N6000 kept most of the FA feature set but swapped in some new features. Incoming ones included:
- A 2 fps internal motor drive to replace the bulky MD-15
- Auto film loading
- Power film rewinding
- Auto bracketing
- Slow and rear-curtain flash
- DX code reading
- Automatic balanced fill flash
- An “analog” (graphic) over/under-exposure display that pops up in manual mode
- Exposure mode indicator in the viewfinder
You could argue that the N8008 was the successor to the “technocamera” FA, but the N8008 was an autofocus camera. Or you might have argued the F4, which is a cross between an F3, an MD-12, and an FA. The departures with the N6000 were somewhat less notable:
- Elimination of interchangeable focusing screens (which were apparently not a popular feature of the FA)
- A new reliance on CPU lenses (AF and AI-P), which allowed the correct aperture to show in the viewfinder without an ADR display
- Loss of program mode for AI-s lenses (due to CPU dependency)
- Loss of matrix metering for AI-s lenses (same)
- Loss of a mechanical shutter speed
- Loss of 1/4000 sec on the shutter
- Change from MS-76 button cells to the somewhat less common CR223A/CR-P2.
But for all intents and purposes, this was “it.” Although Nikon continued to sell (not make) the F3 into the mid-2000s, the only newish manual purpose-built manual focus design was the FM3a, which is little more functionally than an FE2 with a shutter that could also be governed mechanically. It also followed a six-year period in which the N6000 was off the market.
On Earth-399, Nikon made manual focus cameras from 1959 to 2270. But that is also the universe in which “George Washington freed the slaves… Abraham Lincoln was regarded as the father of his country… and George Custer became president of the Indian Federation.” (“Superman… you’re DEAD… DEAD… DEAD,” 1971).
First in/last in (F3AF/F3)
Nikon had always managed to be both early and late to the AF party. The Nikon F3AF emerged in 1983, just three years into the F3 era. In fact, it came onto the scene at the same time the DE-3 High Eyepoint finder came out (this is the thing that makes the F3 into the F3HP, the most popular variant). The F3AF was the first camera to use electronic contacts to control lens focus, using a contact system that is eerily similar to current Nikon lenses – but with a motor-in-the-lens implementation that most people came to associate with Canon. The manual focus version of the F3 proved wildly more popular and became one of the longest-running Nikons in history, with a 20-year run. That is catalog time, not necessarily production time. When it was time for the F4, Nikon was playing catchup with Minolta and Canon on AF, whose amateur cameras were upping the stakes.
The forgotten Nikons (N2020/N2000)
In 1984-1985, just after the F3AF, Nikon made another pair of cameras, one with AF and one without. These were the N2020 (F-501) and its value-engineered little brother, the manual-focus N2000 (F-301). These were essentially a motorized version of the FG. According to lore, the N2000 was a last-minute decision from the accountants. That’s believable since it allowed the company to drop the FG and make two cameras on a common set of tooling. But it cannot actually be true, because the N2000 was the first of the two cameras to be released – and by a year.
Rather than the interchangeable screens of the N2020 (B/E/J), the N2000 had a fixed K screen (split prism plus micro prism collar), a LED shutter speed display (but no AF indications), and no automatic selection between programs (on the FA, this had required a post on AI-s lenses; on the N2020, it required a CPU to tell the camera the focal length). Common to both cameras, though, was a traditional control layout, a coreless drive motor for film advance, auto-loading, an exposure compensation dial, DX coding, plus pretty much everything the FG had – save the +1.5EV backlight button (the N2000/N2020 had an AE lock button that served much the same purpose). One mystery is why the N2020 was typically sold with an AAA battery holder rather than the N2000’s AA – since it is fairly obvious that the battery chamber was designed around AA. The smaller batteries required a special inset tray. But on the plus side, they do shave some height and weight off the assembled body. And the N2000/2020 is a pretty heavy body.
The N2000 is a camera with a level of elegance that we forget about: a large, bright, spartan viewfinder, a normal control layout, and a certain fluidity of shooting. Motor drives can be very important if you are left-eye dominant. Plus normal batteries that you can buy anywhere. Plus it has nice, sharp edges. It’s just not a camera that has the simulated chrome that is so popular with “the kids today.” And yes, by simulated, meaning that pretty much every “chrome” camera post-1980s has plastic covers.
But what about the N6006/N6000?!
The N6006 is something of a hidden gem in the Nikon line; it has most of the things you like about the N8008 (sans 1/8000 top speed, AA batteries, and high-eyepoint finder) in a smaller package. It is actually pleasant to shoot, though it does carry the stigma of using 223 lithium batteries. That might have actually made a difference a few years ago, when you could walk into a drug store and buy CR123As and 2CR5s, but today, all lithium batteries are more Amazon than the corner store.
The N6006 is one of many Nikons that share the AM200 AF sensor array (the others being the N4004/F-401,N5005/F-401s, N8008/N8008s/F-801/F-801s, and the F4. As you might have surmised from the AF performance differences in these bodies, CPU speed and motor torque are huge determinants of speed. The F4 is tops in both CPU and motor power, and the N4004 has the smallest brain and smallest muscles. The N6006 and N8008 are mid-range, and the N8008 has a more powerful motor.
The little brother, the N6000, loses some functionality compared to its AF twin: no spot metering (because that comes from the AF module), no built-in flash (spite?), and a slightly smaller LCD display (that omits the AF confirmation dot, obviously…). But all the same, it is much smaller and lighter. Oddly, it still does support (or for P and S, requires) CPU lenses. As an adjunct for occasional manual focus with otherwise-AF lenses, it is fine; in fact, examples of the N6000 sell for less than the price of any manual-focus-friendly interchangeable screen for any SLR or DSLR. So I would ask, are you better off…
