I'm thinking of selling my loved Canon F1 old body, with a 50mm, 1.4 lens (has both caps, excellent condition) and a 28mm, 2.8 lens (has both caps, excellent condition). The body has one problem, the prism is missing the buttons that you press to remove it. Otherwise, it is in great condition (and the battery works!). I was wondering if anybody had an idea of worth. I'm hoping to sell it and put the $$ towards a camera of larger format. But if I'm not going to get much for it, I might as well keep it. Thanks for your help in advance!
