One-Shot AF for Still Subjects This AF operation is suited for still subjects. When you press the shutter button halfway, the camera will focus only once. When focus is achieved, the AF point will turn green and the beeper will sound. The focus remains locked while you hold down the shutter button halfway, allowing you to recompose the image before taking the picture. For details on the continuous shooting speed for continuous shooting, see Selecting the Drive Mode. Note If [ : Beep] is set to [Disable], the beeper will not sound when focus is achieved. See Lens electronic MF when using a lens that supports electronic manual focusing. 365
