All professional videos use manual focus, anyway, to get it exactly where you want. They do have focus pullers and plan out everything, however.
I can confirm. I was using Canon 550d/T2i yesterday. Quality of movies is wonderful but AF is terrible. If you move camera to other point, AF drives through all range and slowly focusing in small steps finally.
Manual focusing is better idea.
I am still looking for "my perfect" camera, reading tests and reviews. But now K-r is my best candidate. Now I'm choosing "my perfect" lens (:
