Is the zeiss milvus 35mm f 1 4 good for street photography?
Yes, it can work well for street, with one caveat: it's manual focus only. On a full frame body the 35mm is the classic street focal length, so it frames the scene as you'd naturally see it. On an APS-C body it reads more like 52 to 56mm, which is tighter than most street shooters like.
I'd pair it with a full frame body such as the Canon EOS 6D Mark II, the Nikon D750, or the Nikon D780. Street rewards a camera you barely notice, so keep the setup as small as your budget allows. Shooting people in public is also a matter of manners, so read Street before you head out. For the broader choice between sensor sizes, see Is full frame worth it?
