: 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.

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.
