I also use Contax Slrs (RX and Aria) with Zeiss lenses as well as the Konica Hexar AF with its fixed 35 wide f2 lens. For shooting street you don't really need top shelf equipment. You do need reliable equipment. The Contax cameras are/were top shelf and reliable. I don't find them so loud since I shoot mostly in NYC where the street noise seems to drown any shutter noise out. The Hexar is quiet and very fast. It, for me, is the very best camera for street photography since it is small and fast.
