2:AF/AF lock, no AE lock
In the AI Servo AF mode, you can press the <A> button to stop the AF operation momentarily. This prevents the AF from being thrown off by any obstacle passing between the camera and subject. The exposure is set at the moment the picture is taken.
3:AE/AF, no AE lock
This is useful for subjects which keep moving and stopping repeatedly. In the AI Servo AF mode, you can press the <A> button to start or stop the AI Servo AF operation. The exposure is set at the moment the picture is taken. Thus, the optimum focusing and exposure will always be achieved as you wait for the decisive moment.
