Very nice camera. Very grainy Flying Fortress, though. Was the film overexposed?
I enjoy the Summar, the Summitar, and the Summicron. I am probably most partial to the Summitar, although I can't tell much difference between it and the Summicron. The Summar is a really different (and great) look, though, especially for shallow D of F.
Good luck. She is a beauty.
