David, I have the whole line of Zeiss M42 lenses, and I'm using them frequently with my EOS. As I have quit using the auto-metering of the bodies (I have a Seconic 608 and use it all the time, as I don't trust the the metering algorithms of EOS and G1).
The lenses perform very well (I use extensively the 20/2.8 & 200/2.8, and sometimes the 80/1.8), and although I haven't compared them with corresponding EF lenses, I'm absolutely satisfied with the results. The 200mm with a 7-element 2xTC makes a pretty good 400/5.6 If you have any good M42 lenses, it's worth getting an adapter & making some tests...
