History

The FM was the replacement for Nikkormat

Nikkormat was the brand used by the Japanese optics company Nippon Kogaku K. K. from 1965 to 1978 to name two popular but otherwise unrelated series of interchangeable lens, 35 mm film, single-lens reflex cameras.The Nikkormat SLRs were moderately priced, advanced amateur level stablemates to...

 FT3, which had been introduced only a few months prior. It introduced an entirely new compact, but rugged, copper-aluminum alloy chassis that would become the basis for Nikon's highly-successful range of compact semi-professional SLR cameras.

These cameras were intended to provide a more reasonably-priced alternative to Nikon's professional F-series cameras, which at the time was the Nikon F2

Design and construction

The FM was constructed almost entirely from metal and used a mechanical shutter. It was manual-focus-only, with manual exposure control. Being mechanical the FM needs no batteries to operate (though two 1.5 volt LR44 or SR44 cells are required to operate the light meter). The metering system comprised a gallium-arsenide-phosphide photodiode (with 60/40% centre-weighting) that metered through-the-lens at maximum aperture. Its reading was displayed by a "center-the-LED" system using vertically arranged light-emitting diode

s (LEDs) next to +/O/- markers on the right side of the viewfinder that indicated overexposure, correct, or underexposure, respectively. The photographer adjusted the aperture or shutter-speed until the "O" LED illuminated to indicate correct exposure. This system can be traced back to the Nikkormat

The body has dimensions of 89.5 mm height, 142 mm width, 60.5 mm depth and 590 g weight. It was available in two finishes; silver with black trim and all black.

Lens compatibility

The FM accepts all Nikon F bayonet mount

 lenses, with certain limitations or exceptions. Full compatibility requires lenses that support the Automatic Maximum-Aperture Indexing (AI) specification. This includes most Nikon lenses manufactured after 1977. Pre-AI lenses can be used, but only with stop-down metering.
Many newer Nikon and third-party F-mount lenses are also compatible. The only major exceptions are G-type Nikkor lenses, which have no aperture ring and thus no way of properly controlling exposure, and DX Nikkors, which do not resolve an image large enough to cover the 135 frame. All other AF Nikkor lenses will mount and be usable, but autofocus and Vibration Reduction (VR) will not be supported.

 (APS) SLRs, and very old "invasive" Fisheye-Nikkor lenses from the 1960s must not be mounted on the FM, as their rear elements will damage the FM's reflex mirror.

Other features

The FM has a "full information" viewfinder. In addition to the metering LEDs; the viewfinder also displays the set shutter speed and lens aperture to give context to the LEDs. A fixed K-type focus screen with 3 mm split-image rangefinder and 1 mm microprism collar is fitted.

Major system accessories for the FM included the MD-11 and MD-12 motor drive

s; which enabled continuous film advance at 3.5 frames per second, the Data Back MF-12; enabling the imprinting of date and time data on the film, and the Speedlight SB-8E electronic flash; guide number 82/25 (feet/meters) at ASA 100.

Note that there were two distinct versions of the FM, depending on how the FM's light meter (see below) was activated when a motor drive was mounted. The original FM had a rotary switch shutter button collar to switch to motor drive mode when the MD-11 was mounted. The MD-12 activated the meter automatically and the switch was omitted on late (1979 or after) FMs. Nippon Kogaku also took the opportunity to construct late FMs more strongly internally than early FMs.

Design history

Beginning in 1977 with the FM, there was a complete overhaul of Nippon Kogaku's entire Nikon SLR line. The 1970s and 1980s were an era of intense competition between the major SLR brands: Nikon

 and Olympus. Between circa 1975 to 1985, there was a dramatic shift away from heavy all-metal manual mechanical camera bodies to much more compact bodies with microprocessor electronic automation. In addition, because of rapid advances in electronics, the brands continually leap frogged each other with models having new or more automatic features. The industry was trying to expand out from the saturated high-end professional and advanced amateur market and appeal to the large mass of low-end amateur photographers itching to move up from compact automatic leaf shutter rangefinder (RF) cameras to the more versatile and glamorous SLR but were intimidated by the advanced learning curve required to operate a traditional SLR.

Both Nikon's F2 and the Nikkormats were prized for their toughness and reliability. Nippon Kogaku wanted to distill these qualities into a new smaller and lighter design. Nippon Kogaku continued with their unusually high standard of workmanship for amateur level SLRs. For the FM this meant the use of high strength machined metal parts, hardened metal gears, a bearing-mounted film and shutter transport, and a camera assembled to precise tolerances. As a result, the Nikon FM was one of the most reliable 35mm SLR designs ever built.
