Great especially at the price. Solid construction. The lens is very easily removable and put back with a few turns of the mount that holds it. This can be done with one's fingers. By so doing, this adapter can be used instead of the original Canon macro lens mount adapter. The Cannon adapter(s) cost a small fortune, if they can be found at all.

I bought this adapter chiefly to couple my Canon FD bellows to my Canon 20D dSLR. It does a good job of coupling the two mechanically and interposes no image-degrading optics. This sort of adapter cannot provide infinity focus for Canon FD lenses nor can it add autofocus to these lenses. That's not what it's for. However, if you have older FD accessories such as the bellows or extension tubes and lenses and you don't need to focus at infinity (because you're interested in close-up work, for example), then this is the lowest-cost adapter you'll find.

No problems at all -- easy to use, switch on-off lenses.

it works as stated but the element in the adapter causes to much image quality loss. F stops must be set by hand but it will allow the use of your FD lenses on EOS bodies. It works fine on my 20D.

The adapter has a diopter lens built in and may be a problem when using it with some lenses. I use the adapter to connect my bellows to an Elan body. It works perfectly with the bellows.

I bought this to use with a like new Vivitar Series 1 70-210 f2.8 macro Canon fd mount lens. This lens was sharp as a tack on my Canon A1 film camera. I used the adapter to put this lens on my Canon EOS 20d. The exposure and manual focus worked great as far as seeing fine detail in focus on the focus screen. However the resulting photos viewed at 100% were very disapointing requiring a good deal of sharping in Photoshop to get acceptable results. If I had it to do over I wouldn't bother. Maybe I'm doing something wrong.
