Is the nikon z 50mm f 1 8 s good for street photography?

Yes, it's a good street lens. A 50mm is a classic street focal length, and on full frame it frames the scene roughly the way your eye sees it. The f/1.8 aperture also helps when the light drops.

Pair it with a body that stays quiet and unobtrusive. My picks from the lenses' fitting list:

Street shooting rewards a camera you barely notice, so my street guide is worth a read, and the sensor guide explains why a smaller setup is often the better choice.
