First off this is my favorite lens to use (might be cause it is my most expensive as well). Being that it is an extremely fast lens it would be great for sports if it wasnt for the slowish AF. Recently I shot an 6th Grade Elementary basketball game for the coach of one of the teams so that he would have some pictures to give his players at the end of the year. I took along my 3 main lenses one of which being the 85 1.2 II even knowing about the slow AF. In the end the AF still did better then myself manually trying to focus (with apertures between 1.2-2.0).


So now to the question would a camera body that is deamed to have a faster AF system allow the 85 1.2 to focus on the subject quicker?


Current lineup: Canon 40D, 85 1.2 II, 70-200 2.8 IS, 24-70 2.8


Thanks in Advance


P.S. Some of the images may of been out of focus do tothe camera front focusing, thats another reason I would like to upgrade (AF Microadjustment),
