Walter, there's no need for a correction lens in either the Leica or CY mount adapters. The problem with Canon FD/FL lenses is that the register distance requires the lens to be closer to the sensor/film on other cameras to focus correctly at infinity. As this is not possible due to the body limitations, a correction lens has to be fitted to compensate for this. I believe this optical correction also applies to Minolta and Exakta/Topcon lenses - adaptation is purely mechanical in the case of Nikon, Pentax (M42 and K), Leica R, Contax/Yashica, Nikon and Olympus-OM lenses.
