beam. This setting is applicable also for LED-compatible external flashes.

The AF-assist beam is not emitted.
C.Fn IV: Operation/Others
C.Fn-5
0: AF/AE lock
1: AE lock/AF
This is convenient when you want to focus and meter separately. Press
the <YA> button to autofocus, and press the shutter button halfway
to apply AE lock.
2: AF/AF lock, no AE lock
In the Servo AF operation, you can press the <YA> 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.
With Servo AF, pressing the <YA> button starts or stops the Servo
AF. 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.
During continuous shooting, even if you press the <YA> button, the AF
operation will not start or stop.
During continuous shooting without autofocus, using the [1: AE lock/AF]
or [3: AE/AF, no AE lock] setting, the maximum number of frames per
second depends on the AF operation settings and the lens used (p.134).
