Camera nerds have strange obsessions. Among film cameras, the Leica M series of small rangefinder devices is probably top among photo fetishists, who might argue about whether the original 1950s M3 or the current M7 or MP is the optimum design.
But to me, the manual-focus, precision-built electromechanical Nikon FM3A SLR is the real star of these old-school cameras. It was an oddity when Nikon introduced it in 2001—by which time ergonomically-shaped, plastic-bodied autofocus cameras were what almost everyone used, and digital was poised to take over from film almost entirely. (Even the FA of 1983, or the intro-level FG I owned around the same time, had more modern features in many respects.)
But Nikon was intentionally building a modernized retro camera for those fetishists. It offers basic but powerful light-metering, manual focus assistance, fill-flash compatibility, and aperture-priority automation if you want it. But it is also a fully-mechanical machine that will operate perfectly (except for the light meter) without any batteries. All the power to run it can come from energy stored in springs when you ratchet the film advance lever with your thumb, something that's hard to comprehend for anyone who's used to today's battery-sucking digital beasts, or even my 1988 autofocus Nikon F4.
Nikon only made the FM3A for five years, and manufactures nothing at all like it today. (Indeed, almost no one besides Leica makes fully mechanical cameras anymore.) If you can find one, it sells for pretty close to the $800 the model fetched when new, which is still a fraction the cost of a Leica or a top-of-the-line digital Nikon SLR. And it will use most Nikon-mount lenses made between 1977 and quite recently, when the company stopped including aperture rings on their SLR lenses.
I'd compare this rugged Nikon with modern versions of the Fender Stratocaster guitar, or a brand-new fountain pen: the FM3A looks superficially like something created decades earlier, and works pretty much that way too, but it has some clever modern enhancements that smooth the way for enthusiasts or professionals to use it elegantly. It's neat that Nikon ever decided to create it, and like the still-manufactured Nikon F6 film SLR, it's probably among the last of its kind.
