Optics are fantastic. I use it for my Canon EOS Rebel (35mm) and both digital cameras ((don't forget to take into account conversion factor!)). works superb in AF mode, my only complaint is that after about 2 yrs of use, it seems kind of sticky when operating in MF mode. Not terribly bad, but still I'm thinking of having it checked out for a warranty issue since it has a 6 yr warranty.
