•3D-tracking: Select the focus point as described on page 89. In AF-Aand AF-Cfocus 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.

•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-Cmode or when continuous-servo autofocus is selected in AF-Amode, the main focus point remains highlighted after the other focus points have turned off.

A3D-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.
