This is the second and highly improved member of the Fs dinasty. It is THE classic monoreflex camera of all times. Build to last forever it counts 1700 parts and is all mechanical hence fully opperated without batteries.

It is useless to try to say something new about the F2 from technical perspective. There are so many sites on the web that I prefer to send you to one of them: try:   Wikipedia or  CameraQuest
