Taking Photographs-Focus Autofocus When the focus mode selector is set to S (single-servo autofocus) or C (continuous-servo autofocus), the camera focuses automatically when the shutter-release button is pressed halfway. This section describes focus options that are only available in single- and continuous-servo AF. AF-Area Mode AF-area mode determines how the focus area is selected and what happens if the subject moves out of the selected focus area while the camera is still focusing. To select the AF-area mode, rotate the AF-area mode selector. The selected mode is shown by an icon in the top control panel. The following options are available: Mode Icon Description Singlearea AF Dynamicarea AF User selects focus area manually; camera focuses on subject in selected focus area only. Use for relatively static compositions with subjects that will stay in selected focus area. User selects focus area manually, but camera uses information from multiple focus areas to determine focus.
