So I had a perfectly good Nikon F with a plain prism as well as an F2A and F3 but wanted F2 plain prism too so I kept an eye out for that. Was checking out my local CL and spotted yet another F also with a plain prism and thought maybe I could use it to trade for a plain prism F2 since it was offered at a great price - one of those investment options. Just as I got it, a plain prism for the F2 also came up! Now I am not so sure I want to get rid of the second plain prism F since I am not one of those catch and release types.
Besides being good picture takers, it also provides compositional symmetry . . .
