AF-Area Mode

AF-area mode controls how the camera selects the focus-point

for autofocus. The following options are available during

viewfinder photography:

• Single-point AF: Select the focus point; the camera will focus on

the subject in the selected focus point only. Use with stationary

subjects.

• Dynamic-area AF: Select the focus point. 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).

- 51-point dynamic-area AF: Choose when photographing subjects

that are moving quickly and can not be easily framed in the

viewfinder (e.g., birds).
