Nice presentation, besides a killer subject the exposure is so perfectly placed in all these. This seems especially sharp, compared to the Schneider convertible. I think i almost like the other interior image a little more for that reason. This is a pretty up front and gritty take, which has its own qualities to like.
Yeah, the convertible isn't a super sharp lens. I now have a 210mm Symmar-S that is much sharper. The Mamiya lenses are tough to beat, though. My 180mm is even an older, non-C lens.
