So, it looks like this is the biggest Nikon news coming out of a somewhat disappointing PMA 2009 – the F-mount we know (and love?) has hit it’s half-century.  Of course, today’s do-it-all AF-S and VR F-mount lenses don’t work on older cameras, and the newer consumer cameras can’t meter with the older Nikkors, but…

Evolution of the Nikon F-mount

• Introduced on Nikon’s first lens-interchangeable SLR, the Nikon F (1959)
• Auto aperture indexing enables automatic setting of maximum aperture (1977)
• Program auto exposure mode compatibility (1981)
• Aperture information exchange with the camera body through CPU communication (1983)
• Autofocus compatibility (1983)
• Digital SLR cameras compatibility (1995)
