This camera is pretty old, made in 1975. The body is all mechanical. The prism finder, that big thing on top, contains a light meter. This was the second in Nikon's line of professional grade SLR's. In it's time, this camera was the workhorse for photojournalists. There's an old joke that if an F2 looks like it has been through a war or a riot, it probably has. Some people are of the opinion that this was the best 35mm camera ever made. I got it pretty cheap. It's nice to give a legend a good home.
