• 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 AF-S focus mode, the camera will give priority to portrait subjects. • Auto-area AF: The camera automatically detects the subject and selects the focus point; if a face is detected, the camera will give priority to the portrait subject. The active focus points are highlighted briefly after the camera focuses; in AF-C mode, the main focus point remains highlighted after the other focus points have turned off. AF-area mode can be selected by pressing the AF-mode button and rotating the subcommand dial until the desired setting is displayed in the viewfinder and top control panel. AF-mode button N Sub-command dial Top control panel Viewfinder A 3D-tracking When the shutter-release button is pressed halfway, the colors in the area surrounding the focus point are stored in the camera. Consequently 3D-tracking may not produce the desired results with subjects that are similar in color to the background or that occupy a very small area of the frame. 101
