This is convenient when you want to focus and meter separately. Press

apply AE lock.
2: AF/AF lock, no AE lock
During Servo AF, you can press the <
A
> button to pause 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.

This is useful for subjects that keep moving and stopping repeatedly.
During Servo AF, you can press the <
A
> button to start or stop the
Servo AF operation. The exposure is set at the moment the picture is
taken. Thus, you can set your camera to always maintain the optimum
focusing and exposure and wait for the decisive moment.
