Actually what I mean as slow is the actual shutter lag, this shows it much better. http://www.impulseadventure.com/photo/shutter-lag.html combine that with focus lag and its major, my MKIIn is .004 where as the 5D is .075 the 20D is .076 so there real close, 10D is .091, and what i was talking about the 3200 for 100 of a sec is trying to capture any action above 100 of a sec you need to have high iso,and that introduces noise, unless your running flash in manual mode at 160th or 200th in dim lite is fine, but that little bit of shutter lag does introduce trails, unlike my mkIIn or MKIII hope that explains it better.
