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-A and AF-C 

focus 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-point dynamic-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-point dynamic-area AF: Choose when photographing subjects that are moving 

unpredictably (e.g., players at a football game).

- 39-point dynamic-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-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.

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.
