The F2 achieved "hockey puck" status from Marty Forster the guy who coined
the term the FM's and FE's were work horses used by everybody just before
Canon Kicked in and visibly took over. I've shot more pictures with a Nikon
FM2 then by far any other camera. Part of the reason was the compact not
expensive MD11's and Md12 motor drives.
