Is the ttartisan af 23mm f 1 8 good for street photography?
Yes, I think it's a good street lens. On APS-C it frames like a 34mm on full frame, a natural field of view for scenes you'd walk through. At f/1.8 you get a bit of background separation, and autofocus means you don't have to fiddle while a moment passes. It isn't stabilised, so keep your shutter speed up.
My picks for pairing it with a body, all from its compatible cameras:
As my street guide says, a camera people don't notice matters more than megapixels. Also see sensor sizes, since APS-C is plenty for this kind of shooting.
