Matt, I've just added the 90 APO to my armoury and whilst it is optically excellent, I would say it is not as good mechanically as the 75. This is for two reasons:- 1) the aperture ring on the 90 is loose, making it too easy to accidentally knock it away from the selected aperture (the aperture ring is right next to the focussing ring). 2) the focus mount is stiff when focussed at about 1.2 meters. This makes it hard to make fine focus adjustments on close-ups. Granted, this may wear in with use, so I've taken to regularly twisting the mount to help it along. It is very likely that these characteristics are particular to my lens only but I thought I'd better let you know. Primarily, I bought the 90 to use on an M2 for portraiture so will often use the close focus range. I must emphasise though, that I would still buy this lens again, given the choice (especially as the M2 does not have 75 framelines). Bottom line though, if I had a preferrence between the 75 and 90, it would be the 75 as it focusses closer which is a distinct advantage in portraiture. Paul.
