my 550d mode dial as been a pain since i bought the camera a year ago,i take a lot of wildlife pics which means a lot of moving about,i usually keep the dial on tv mode,my problem is the dial moves itself usually to manual sometimes to p,today i missed out on 2 bird shots both with the settings moving to manual and a 1/13 sec which ened up with blurred shots,is there any way to stop this ?
