I spent awhile at the rental dept. at Keeble &Schuchat (sp?) in Palo Alto looking at their Mamiya II with 80mm lens. I really just cannot see how one can do quick focusing for street work. I've heard great things about the lenses for these, but what good is that going to be when you can never be sure if what's going on the film is what you really want (like with an slr) and if it's going to be focused correctly.
