Hi John and others when I tried to use a 58mm polarizer with a rubber hood on a 52mm Tokina 3.5-45. 28-70mm zoom with a step up ring from 52 to 58mm , my SFX could not auto focus anymore. When I remove the rubber hood, it works. The motor of the SFX (SF1) seems not to be strong enough for the filter and hood.
