A couple from a newly acquired C/Y 28/2.8. My initial impressions are that it resolves a hair less detail centrally than my G28, though on NEX the edges might be a bit better with the C/Y. I also feel for some reason that it has less DoF than I'd expect at a given aperture. I know some have described that to be the case with the Contax 28/2 and it's heavy FC, but I thought the 28/2.8 was supposed to have a pretty flat field.
