f: Selecting the AF ModeN
This AF mode is for moving subjects
when the focusing distance keeps
changing. While you hold down the
shutter button halfway, the subject
will be focused continuously.
The exposure is set at the moment
the picture is taken.
In the d/s/f/a/F shooting
modes, AF is also possible by
pressing the <p> button.
AI Focus AF switches the AF mode
from One-Shot AF to AI Servo AF
automatically if the still subject starts
moving.
After the subject is focused in the
One-Shot AF mode, if the subject
starts moving, the camera will detect
the movement and change the AF
mode automatically to AI Servo AF.
AI Servo AF for Moving Subjects

With AI Servo AF, the beeper will not sound even when focus is achieved.
Also, the focus confirmation light <o> in the viewfinder will not light.
When focus is achieved in the AI Focus AF mode with the Servo mode
active, the beeper will sound softly. However, the focus confirmation light
<o> in the viewfinder will not light.
