Is the voigtl nder nokton vintage line 35mm f 1 5 aspherical good for street photography?
Yes, I think it's a good street lens. My street guide says the best kit is one people don't notice and one you can shoot without thinking, and a 35mm f/1.5 on a Leica M body fits that well. It's manual focus only, so it takes some practice, but once you know your distances it's quick. The wide aperture also helps in dim streets.
Good bodies to pair it with from the catalogue:
If you only shoot black and white, the Leica M10 Monochrom is worth a look.
Whatever you shoot, check the local rules on photographing people, and read the street guide's section on people on being open about what you're doing.
