Choose single-servo AF for landscapes and other stationary sub-
jects. Continuous-servo AF may be a better choice with erratically-
moving subjects. Manual focus is recommended when the camera
is unable to focus using autofocus.

Autofocus can also be activated by pressing the
B button.
APredictive Focus Tracking
In continuous-servo AF, the camera will initiate predictive focus tracking if
the subject moves toward or away from the camera while the shutter-
release button is pressed halfway or the B button is pressed.
This
allows the camera to track focus while attempting to predict where the
subject will be when the shutter is released.
