I want to note that according to what I've read on the fredmiranda (sp) forums many of the ZE lenses will focus past infinity (not sure if infinity matches infinity mark). I think I read that the official comment on this (from zeiss) is that it allows for expansion due to heat.

Hi,
My Voigtländer 40/2 isn't very accurate in that regard - it seems that the 'infinity' setting is not actually infinity. The Zeiss 21/2.8 however, is extremely accurate and child's play to focus. You can literally set that lens to F5.6/5m and use it like a Lomo. The Zeiss 85/1.4 and 50/2 are also very good, sharp lenses and admirable for landscape work - and although I might believe they are superior to Canon/Nikon lenses in some respects, the differences are quite small. And plenty of people would disagree with this assertion, anyway.
Also, one would assume you won't always want to focus at infinity. And, as has been said, you can use an AF lens in MF mode, so it's just a matter of turning AF off. At the end of the day, using a tripod, spirit level and live view will probably improve optical errors to a greater extent than a shift to MF lenses.
