great!June 11, 2008 Michael Neisius(Torrance, CA USA) Well made and works great. Now I want more old lenses for my new Canon XSi!
Another one to watch out forAugust 23, 2008 J. Thurman I already posted a review of an M42 to EOS adaptor with an aperture stop down ring. I would recommend you find one without this. It can get in the way of the aperture pin on the lens, causing you to lose the ability to focus to infinity, or cause you to cut it off. The rim only makes it so you can't open the aperture at all while on the adaptor, and who wants that? There is another adaptor on Amazon now without a rim, the one made by Bower, I have it and it works flawlessly on my 30D. Buy this only if you have a lens that cannot switch between M and A mode because you'll need the rim to stop down the aperture.
