Having read Putts review about this lens, on a whim I bought one. I know there are adapters out there for the FD to M mount to use on my M9. I didn't realize however that I would have to scale focus! Doesnt make sense to use scale focus with a normal lens. Is there any way to use this lens focus coupled on a another digital camera with a different adapter? I've always wanted a Canon A-1 since it was my first SLR. Perhaps film is my only hope of using this lens. Yikes! Thanks for looking!!
