Is the nikon z 35mm f 1 4 good for street photography?
Yes, I think it's a good street lens. 35mm is a classic street focal length: wide enough to take in a scene, close enough to tell a story. The f/1.4 aperture also helps when the light drops.
On a full frame Nikon Z body it frames as a true 35mm. On an APS-C body it behaves like about 52mm, which is tighter, so you'd stand a little further back.
The Street page says small and quiet beats megapixels, so I'd pair this lens with one of the smaller APS-C bodies, like the Nikon Z30 or the Nikon Z50 II. The sensor guide explains why APS-C is plenty for this kind of shooting. And before you start, read a word on people.
