Focus mode

Camera autofocus systems work in one of three modes: single-shot autofocus (usually abbreviated to ‘S’), continuous autofocus (‘C’) and manual focus (‘M’). If you’re taking one photo at a time, use single-shot autofocus – the camera will focus once and then fire. If you’re using continuous shooting mode, use continuous autofocus – the camera will keep refocusing all the time the shutter button is held down.
