I am interested in "Street Photography", although I feel I need advice from more EXPERIENCED "Street Photographers", especially the "DO's & Don'ts", and also a would a DSLR or P&S be more advisable.
I presently have a Nikon AFS-C DX D3300 with a 35mm, 50mm, 18-55, 55-200 lens.
I have read other Posts here at UHH, just would appreciate some "FRESH" insight and Advice on "Street Photography".
Leica M3, oh, you mean modern digital camera.
The traditional focal length for Street Photography for APS-C format would be ~24mm. That is close to 35mm for a FF or 35mm Film camera. If I were to seriously get into Street Photography I might look at a good (high-end-ish) digital Rangefinder type camera. Leica, Canon, and Nikon have had such models. And I don't actually mean simply a P&S. There are a few actual rangefinders, similar in many ways to a MILC.
