•
The camera focuses on a point selected by the
user. If the subject briefly leaves the selected point,
the camera will focus based on information from
surrounding focus points.
•
This option is only available when photo mode is
selected and [Continuous AF] is chosen for focus
mode.
•
Use for photographs of athletes and other active
subjects that are hard to frame using single-point
AF.
•
The size of the area used for focus can be selected
from S (small), M (medium), and L (large). S is the
smallest and L the largest.
•
[Dynamic-area AF (S)]: 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).
•
[Dynamic-area AF (M)]: Choose when
photographing subjects that are moving
unpredictably (e.g., players at a football game).
•
[Dynamic-area AF (L)]: Choose when
photographing subjects that are moving quickly
and cannot be easily framed in the selected focus
point (e.g., birds).
