The Nikon FG is an interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Nippon Kogaku K. K. (Nikon Corporation since 1988) in Japan from 1982 to 1986.
The FG was the successor to the Nikon EM camera of 1979 and the predecessor of the Nikon FG-20 of 1984. These three cameras comprised Nikon's first family of ultra compact 35mm SLR camera bodies. Although the FG had a much less advanced shutter than the more expensive Nikons of the day, it had a very sophisticated electronic design compared to earlier electromechanical Nikons.
The FG's metering system is controlled by a micro-computer which measures center-weighted brightness, using a sensitive silicon photodiode (SPD) sensor. The metering system performs 'instant stop down metering', where the meter reading is taken after the lens is stopped down but before the mirror flips up and the shutter opens.
In 'P' (Programmed AE) mode, the micro-computer calculates stepless aperture (f/stop) and stepless shutter speed using pre-programmed values.
In 'A' (Aperture Priority AE) mode, the micro-computer calculates a stepless shutter speed for a given user-selected aperture value.
In 'M' (Manual Exposure Control) mode, the user selects both aperture and shutter speed, and the metering system provides a suggested shutter speed (indicated in the viewfinder) for the selected aperture.
The focusing screen is a standard Nikon 'K-type' screen with:
Displayed on the right side of the viewfinder are:
The FG was also Nippon Kogaku’s first amateur level SLR to have through-the-lens TTL off-the-film (OTF) electronic flash automation. However this technology was first introduced with the Olympus OM-2 in 1976. and was also used previously in the Nikon F3 introduced in 1980. TTL OTF flash exposure control is more precise than previous methods as it measures the flash exposure at the film plane rather than at the flash itself. Correct flash exposure is achieved via a SPD cell at the base of the mirror box, which measures light reflected back from the film plane.
The FG can only connect to flashes via the hot shoe connection, as it lacks a PC sync socket. Flashes which do not have a hot shoe can be used with a hot shoe-sync cord adapter.
The FG can be used with any dedicated Nikon speedlights (flashes) which support TTL flash exposure, and any non-dedicated flash units in either automatic or manual modes.
