button halfway, the camera will focus only once. While you hold
down the shutter button halfway, the focus will be locked. You can
then recompose the shot if desired.

you press the shutter button halfway, the camera will focus in the
same way as One-Shot AF. Then if the subject starts to move, the
camera switches to AI Servo AF and focuses continuously.
