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.
