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).
