Al Servo

April 08 14:55 2017

Normally, the autofocus locks onto the subject (or what you are taking a picture of) and stays locked. But, with Al Servo or Continuous autofocus, the autofocus continues working. With a single autofocus mode, if the subject (or the camera) moves, the shot will be out of focus. With Al Servo or continuous autofocus, the autofocus system will continue focusing until you take the photo, so the subject is still sharp, even if they move. This camera setting is essential to understand for photographing moving objects.
