35mm cameras which used to be thought ideal for street photography were small, semi-auto Japanese rangefinders with fixed lenses of around 40mm. Canonet QL 17 and 19, Konica C35, Ricoh 500G, Olympus 35RC, Minolta Hi-matic series, there were quite a few. The Canons are quite in demand and thus fairly expensive but the others are affordable from eBay. I’d go for the Ricoh. Decent quality, never as iconic as some of the others, quite a bright viewfinder with a clear rangefinder.
