I found a listing for a sigma 50-500 but it says it comes with a sigma 35mm, is the sigma mount the same as a canon 40d?
I can't find much info on the net, I can't even find a sigma mount 50-500.
the price is $100 with the camera, could this be a Sigma AF 50-500 /4-6.3 APO EX DG HSM or did sigma make old versions that were not sought after?
