Nikon Cameras Nikkormat FT3

1977

The Nikkormat FT3, manufactured for only several months in 1977 (but still available new from dealer stock in 1978), had the shortest production run of any Nippon Kogaku SLR. The FT3 was essentially identical to the FT2 except that it supported Nikkor lenses with the Automatic Indexing (AI) feature (introduced 1977). AI Nikkor lenses had an external "meter coupling ridge" cam on the lens aperture ring that pushed on an external "meter coupling lever" on a ring surrounding the FT3's lens mount flange to transfer lens set aperture information.

Note that most AF Nikkor autofocusing lenses are also AI types. They will mount and meter properly under manual focus on the FT3. However, Nikon's most recent SLR lenses, the AF Nikkor G and AF Nikkor DX types, are not AI types. They will mount, but will not function properly.

The FT3 was little more than a stopgap placeholder, awaiting the release of the first of the completely redesigned Nikon compact F-series SLRs, the all-new Nikon FM, with a more compact chassis, in late 1977.

The metering system was considered one of the best on the market at the time, as the Nikkormat FT3 remained a very popular camera with professionals and amateurs alike.
