sigma 28mm f1.8 w/aperture ring?
I want to purchase this lens but when I go to the Sigma site it is shown with an aperture ring while when I go to purchase one with a sony mount it is pictured without the aperture ring. I'd like the aperture ring. What's going on here?? I'm guessing that the one with the aperture ring is the most recent version of the lens and I wonder if the auto focus back focus problem that has been noted with this lens is fixed with the newest version of the lens.
