S Selecting the AF PointN
When shooting a portrait up close, use One-Shot AF and focus
the eyes.
If you focus the eyes first, you can then recompose and the face will
remain sharp.
If it is difficult to focus, select and use the center AF point.
The center AF point is the most sensitive among the nine AF points.
Also, with a fast lens from f/1.0 to f/2.8, high-precision focusing is
possible with the center AF point.
To make it easier to focus a moving subject, set the camera to
automatic AF point selection and AI Servo AF.
First use the center AF point to focus. If the subject moves away
from the center AF point, the other AF points will continue to focus-
track the subject automatically.
