If you are focusing on a stationary object, why are you using AI-servo (focus tracking) instead of one-shot AF in the first place? Under what light conditions were you shooting. In my (very) short experience with the 1V, AI-servo had absolutely no problem tracking moving subjects. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
