    I have just got hold of a 2nd hand sigma lens but dont know which mount it has. It is a Sigma AF DL Macro Super 70–300 mm f/4–5.6..I think it is the AF but it doesnt actually say on it. The only clue I have is the rear lens cap says on it...for Minolta AF but it might be a universal cap maybe. There are three minolta mounts I know of MC, MD and A......My question is how to identify the mount and will it be compatible with my Canon EOS 80D, and if not is there a adaptor to convert it. I have obviously tried to fit it on my Canon but it will not fit so an adaptor will be neccessary but which. I have uploaded some pics of it...any help appreciated

    i googled minolta af rear lens mount and they look the same so my guess would be thats what it is, i know nothing about minolta so its just a guess by images
