Is the leica summicron m 50mm f 2 good for street photography?

Yes, I think the Summicron-M 50mm f/2 is a good street lens. It's small, and street photography rewards a camera people don't notice and one you can shoot without thinking. Manual focus is part of the deal, so it suits people who like to slow down and pre-set their distance.

It fits a long list of full frame Leica M bodies, including the Leica M10-D and the Leica M-E (Typ 220). Pick the one that feels right in your hand.

If you want more sharpness and can spend more, the APO-Summicron-M 50mm f/2 ASPH is the sharper option. This one is the cheaper of the two.

Whatever lens you use, be open about what you're doing with people. See Street for how I'd handle that.
