Just got my 5D2 last week and now I can see using LiveView that my Contax 35 f/1.4 doesn't quite reach infinity with either of the two adapters I have. I currently have no mirror issues with the lens.
I'm not overly fussed as this is not really my landscape lens, but it would be nice to be able to use it for that and not be restricted. I can't remember if this has been explained before in the Official Zeiss 35 1.4 thread but I cannot find it and a search showed no results.

Infinity adjustment on Y/C lenses is relatively easy:
- Remove the rubber grip from the barrel (just slide it off).
- Loosen the screws on the barrel a bit.
- Rotate the barrel by a small amount and fasten the screws.
- Check infinity.
- Reinstall the rubber.
A few iterations may be required.
I don't know whether this procedure applies to all Y/C lenses, but I cured a few in this manner.
Perfect thanks! just rolled back the rubber, there are 7 screws around the barrel, 6 evenly spaced around in a line, and one just infront of the screw which sits at the top of the lens as you look down on the camera. Do I loosed that odd one, or all six or all seven?! I don't want to loosen something that I shouldn't

Loosen the six screws. The odd one does not ring a bell, and I would not touch it.
Thanks Toothwalker, much appreciated. I unfortunately do not have a screw diver which I can get enough torque through to loosen the very tight screws so I think I'll leave the lens alone
Get a set of Wiha brand precision screwdrivers, or perhaps a set from ifixit.com that they use to take apart iphones and such. You just need the exact right size.
Finding the perfect adapter only works if you're buying a used lens that you know for certain has never been adjusted for infinity -OP should buy the perfect adapter but be prepared to adjust in any case -

Yes, my copy came with a fotodiox pro adapter which was too thick to achieve infinity focus.
Got another adapter, HappyPageHK, and works perfectly.
