I'm 6x6 format, myself. I prefer that format over anything else because I just naturally see in squares. With 35mm, I always end up cropping off one end or the other (empty, meaningless space.) I have a Bronica SQ-Ai, and used to have a Hassey (which I loved, but had to give up.) Really, I don't care the kind of camera as long as it's solid and dependable. It's the neg size / shape that I'm after.
