AF-Area Mode AF-area mode determines how the focus point is selected in autofocus mode. To select the AF-area mode, rotate the AF-area mode selector. The following options are available: AF-area mode selector N Mode Description K Singlepoint AF User selects focus point manually; camera focuses on subject in selected focus point only. Use for relatively static compositions with subjects that will stay in selected focus point. • In continuous-servo AF (pg 72), user selects focus point manually; if subject briefly leaves selected focus point, camera will focus based on information from surrounding I Dynamicarea AF points. Number of focus points used can be selected from 9, 21, and 51 using Custom Setting a3 (Dynamic AF area, pg. 285). If 51 points (3D-tracking) is selected for Custom Setting a3, focus point will be selected automatically using 3D-tracking. • In single-servo AF, user selects focus point manually; camera focuses on subject in selected focus point only. Camera automatically detects subject and selects focus point. If type G or D lens is used (pg. 370), H Auto-area AF camera can distinguish human subjects from background for improved subject detection. In single-servo AF, active focus points are highlighted for about one second after camera focuses. Active focus points are not displayed in continuous-servo AF. 74
