Nikon F mount

Nikon firstly introduced the F-mount in 1959 for film, full frame reflex cameras when there was no autofocus and no automatic exposure. The mount evolved on electronic communication to support these and other features between camera and lens over the years: there are infact a whole lot of "variants" (like AI, AI-S, AF-S, AF-D, ..)  to designated if and how some functions are supported (an in-depth article is available in KenRockwell site).

This mount is compatible both for full frame (FX) and APS-C sensor size (DX) lenses.
