Fro FIlm Project Episode #005 Nikon Film Camera Progression
Starting in 1980 with the introduction of the Nikon F3 a new Pro flagship camera would be released every 8 years. Think about that, where today new pro bodies come out pretty much every two years back then we went 8 years between new release.
You had the Nikon F3, F4, F5 and F6 from 1980 to 2004. That is amazing, the progression of bodies and the changes that happend were vast. Today we get changes but they are not as huge as they once were.
