For my street-shooting I use one of my Nikon F3HP cameras, (with MD-4 motordrive). I generally use my Nikkor ED 180mm lens when I want to be "sneeky", or my Nikkor 35mm f/2.8 lens when I want to include the surroundings. My "walk-about" lens is a very nice Tokina AT-X 28-85mm f/3.5-4.5 lens. Sometimes I even plug my waist-level finder onto my F3, and pretend to be just "foolin'-around" with my camera, in-order to get people's "guard" down.
