AF-Area Mode
Choose how the focus point for autofocus is selected.
• Single-point AF: Select the focus point as described on page 108;
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 108.
In AF-C focus mode, 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:
- 25-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).
- 72-point dynamic-area AF: Choose when photographing subjects
that are moving unpredictably (e.g., players at a football
game).
- 153-point dynamic-area AF * : Choose when photographing
subjects that are moving quickly and can not be easily
framed in the viewfinder (e.g., birds).
