Thanks for sharing that Wayne! I think the CV draws better to my eye, but the Leica and Zeiss come close. I found the Zeiss non-APO behaviour a bit disappointing, but actually it isn't far behind the two APO ones, and is better than most (if not all) the other non-APO ones in the league.
A bit of an aside - how does the 90/2 AA go as an occasional macro lens paired with the Elpro 3? How high a magnification can you get while retaining still great IQ?
cheers, dave
