AI Focus AF switches the AF operation from One-Shot AF to AI
Servo AF automatically if a still subject starts moving.
After the subject is focused in One-Shot AF, if the subject starts
moving, the camera will detect the movement, change the AF
operation automatically to AI Servo AF, and keep tracking the
moving subject.
Under low-light conditions, when you press the shutter button halfway,
the built-in flash may fire a brief burst of flashes. It illuminates the
subject to enable easier autofocusing.

AF-Assist Beam with the Built-in Flash
When focus is achieved with AI Focus AF with the Servo operation active,
the beeper will continue beeping softly. However, the focus confirmation
light <

locked in this case.
AF-assist beam will not be emitted by the built-in flash in <

The AF-assist beam cannot be emitted with AI Servo AF operation.
The effective range of the AF-assist beam emitted by the built-in flash is
approx. 4 meters/13.1 feet.
In Creative Zone modes, when you raise the built-in flash with the <
I

button, the AF-assist beam will fire when necessary.
