Servo AF for Moving Subjects This AF operation is suited for moving subjects. While you hold down the shutter button halfway, the camera will keep focusing on the subject continuously. When focus is achieved, the AF point will turn blue. The beeper will not sound even when focus is achieved. The exposure is set at the moment the picture is taken. For details on the continuous shooting speed for continuous shooting, see Selecting the Drive Mode. In < > mode, by default, the camera automatically switches to Servo AF in response to subject movement. Caution Depending on the lens used, the distance to the subject and the subject's speed, the camera may not be able to achieve correct focus. Zooming during continuous shooting may throw off the focus. Zoom first, then recompose and shoot. 366
