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:
- 9- or 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).
• 3D-tracking: Select the focus point as described on page 108.
In
AF-C focus mode, 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.
