I\'d say they will be optically very similar, quite an accomplishment given ROHS. If you don\'t want distortion the Leica 19/2.8 ROM is the way to go (with modification). The Leica beats the distagon from 5.6 smaller in all but extreme corners (at least going by MTF\'s, I don\'t have either... yet).
The old CZ21 is the resolution king, by far, all over the frame, at all apertures.
Exactly. And here we have MTFs that show the new one convincingly beating the old one. It is so obvious to me. Can you see it too, Mark?
For instance:
Zone A wide open on the new one will kill Zone A wide open on the old.
Zone C at 5.6 on the new one is considerably higher resolution than Zone C at f5.6 on the old one!
Anyone who has owned and shot a lot with the old version must find this as remarkable as I do. Some recent lenses have come close (sort of) to the original CZ21, but this one is better, and by a very significant margin, and where it really matters.
