• 3D-tracking: Select the focus point. In AF-A and AF-C focus modes, the camera will track subjects that leave the selected focus point and select new focus points as required. Use to quickly compose pictures with subjects that are moving erratically from side to side (e.g., tennis players). If the subject leaves viewfinder, remove your finger from the shutter-release button and recompose the photograph with the subject in the selected focus point. • Group-area AF: The camera focuses using a group of focus points selected by the user, reducing the risk of the camera focusing on the background instead of on the main subject. Choose for subjects that are difficult to photograph using a single focus point. If faces are detected in single-servo AF (AF-S or singleservo AF selected in AF-A), the camera will give priority to portrait subjects. • Auto-area AF: The camera automatically detects the subject and selects the focus point (in the case of portrait subjects, the camera is able to distinguish the subject from the background for improved subject detection). The active focus points are highlighted briefly after the camera focuses; in AF-C mode or when continuous-servo autofocus is selected in AF-A mode, the main focus point remains highlighted after the other focus points have turned off. 104
