<p>I wonder if anyone could kindly help me with a suggestion about FD-EOS adapter. I recently bought an adapter that has no optics in the middle, it's just a ring. Now, I've found this working only with FD 200mm f2, while some other lenses (FD 85mm 1.2L, FD 20-35 f3.5L and FD 17mm f4) I have tried don't work with it at all. FYI, I have had tried them on 40D and 60D. Using this adapter I can only see an unfocused view and it doesn't change in any point of the focusing ring's position. Can anybody please suggest if it's happening because my adapter doesn't have the correction glass in it? Would it help focusing if it had the optics in it? In other words, does anybody have experience of properly focusing with any of these lenses on an EOS body? If yes, which brand of adapter works best? </p>
