I like the Minolta Hi-matic rangefinders for street photography, especially the Hi-matic 7s. Decent lens (45mm f1.8), compact enough, reliable, very affordable and extremely comfortable to use. And film loading is a quick and easy affair, which I think is important for street photography work.
I think a fixed lens rangefinder is your best bet, Canon and Minolta made a number of models, Minolta more extensive than Canon. I have a use the
QL 1.7 fast 50mm lens, leaf shutter, shutter speed priority, manual override, 48mm filters, bright parallax corrected rangefinder.
