The Nikon FM is a mechanically operated, interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured in Japan between 1977 and 1982 by Nippon Kogaku K. K. (now Nikon Corporation). The FM was the replacement for Nikkormat FT3, which had been introduced only a few months prior. It introduced an entirely new compact, but rugged, copper-aluminum alloy (duralumin) chassis that would become the basis for Nikon's highly successful range of compact semi-professional SLR cameras.
