I will be taking some shots of a soccer game. I plan to use AI Servo AF because the Manual says: "while you press the shutter button halfway, the camera focuses continuously...This AF mode suits moving subjects when the focusing distance keeps changing"
It would also seem advantageous to select a Continuous drive mode which takes continuous shots "while you hold down down the shutter button fully."
How do these two functions work together? Do I hold the shutter button halfway, depress fully taking a series of continuous shot, go back to halfway to focus again?
