Great.I have an old Tamron 500mm mirror lens that I bought in 1985. I had long thought it was now useless. But no! This adapter actually works so I can use it on my Canon EOS 400D camera. I just set the mode to aperture priority and reduce the exposure by one stop and then use as before. (I set the exposure to one stop under because the lens always seemed to work at a 5.6 aperture setting instead of the 8.0 it was meant to be).So now I have my old lens.
