I think that the whole camera gear for street photography conversations are blown out of proportion. It isn’t necessary to have the latest model. A camera is just a tool. You are responsible for choosing the composition and exposure.
Forget the camera, forget the lens, forget all of that. With any four-dollar camera, you can capture the best picture. Alberto Korda
The only exception to this in street photography might be the lens that you use. If you are looking to create straight ahead street photography, it should always be with a wide angle lens. Not zooming in on your subject from afar.
