How much is the pentax 2 6x7 camera?

While little on the F was truly new, it was a well-made camera, and adhered closely to the control scheme of the Nikon rangefinder cameras, Asahi Pentax, etc. Instead of the M42 screw mount, Nikon introduced the F-mount bayonet lens mount system, still in use in a much modified form today. The F was a modular camera, in which various parts (pentaprism, focusing screen, film back, etc.) could be changed in order make it better fit the task. It was the first 35 mm camera offered with a successful motor drive system. Unlike much of the competition, it was released with a full range of lenses from 21 mm to 1000 mm focal length. Subsequent top-of-the-line Nikon models carried on the F series, which has as of 2005 reached the F6 (although this has a fixed finder).
