The Zenitar 50mm f1.2 is an a-psc normal lens with a very fast aperture and very sharp but vintage looks. This lens is a normal lens. It is very sharp with vignetting only on a full frame. But the frame itself is very warm and modern. With vintage flares.
This lens does not cover Full Frame completely, but has just a small but hard vignette, Super 35mm and m4/3 digital sensors are covered. 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.
