Hi Oren,


I think the camera automatically switches from the AI Focus mode to AI servo mode when it senses moving objects based on the focus point.


Some tips:


High ISO, Tv mode -shutter speed: 1/500 atleast (varies on the available light), high speed continuous shooting.


Finally a USM L telephoto lens for a very good reason. They focus very quickly and accurately.
