The Nikon FM is a mid-range 35mm film SLR camera developed in the late 1970's to replace the Nikkormat FT3.  It's a camera built for amateurs or serious enthusiasts, that enjoys a reputation of great construction with superb reliability thanks in part to a 100% mechanical shutter.  The body comes in both black and chrome versions.

The FM utilizes the Nikon F-mount and can mount just about every lens ever created by Nikon. The FM has a stainless steel Nikon F-mount that accepts that even accepts non-Ai lenses; unlike most Nikon bodies made later on, the FM's metering 'aperture follow tab' can be flipped back out of the way so non-AI F-mount lenses can be mounted without causing damage (stopped down metering via depth of field preview lever is required).
