The Zenitar 50mm f2 is a normal lens with fairly slower aperture and very sharp but vintage looks. This lens is a normal lens. On full frame itself is very warm and modern. With vintage flares. Vignetting is awesome, there is none! At all, even for full frame …this lens is just a half stop slower than the 1.7 and it offers the benefit of focusing a few inches closer for those wanting to give themselves a different versatility or a B lens option .
This lens does cover Full Frame, Super 35mm and m4/3 digital sensors. This lens is in EF, matches well enough to the Zuiko lenses, which offer a little more yellow vs. amber tones found in the Zenitar lenses.
