I will say that I am NOT shooting AI Servo I am shooting One Shot - Center focus point, and I am about 50/50 with focus right on the subject and nothing is in focus OR it is totally back focused.
I am shooting with either a 24-70L or the 70-200L and both work fine on the 30D and there are 50% keeper rate on the Mark III.
I have found that most large Japanese companies will never admit guilt for anything. For that matter, most North American companies wouldn't either, but we have lots of consumer groups, and regulations to go through. They don't have that in Japan.
