AF-Area Mode
Choose how the focus point for autofocus is selected.
•Single-point AF: Select the focus point as described on page 96; the camera will focus on the subject in the selected focus point only. Use with stationary subjects.
•Dynamic-area AF: Select the focus point as described on page 96. In AF-Aand AF-Cfocus modes, the camera will focus based on information from surrounding focus points if the subject briefly leaves the selected point. The number of focus points varies with the mode selected:
-9-pointdynamic-area AF: Choose when there is time to compose the photograph or when photographing subjects that are moving predictably (e.g., runners or race cars on a track).
-21-pointdynamic-area AF: Choose when photographing subjects that are moving unpredictably (e.g., players at a football game).
-39-pointdynamic-area AF: Choose when photographing subjects that are moving quickly and can not be easily framed in the viewfinder (e.g., birds).
•3D-tracking: Select the focus point as described on page 96. 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.

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 the same color as the background or that occupy a very small area of the frame.
