Module alone, since other related camera functions—like the
Release modes—directly affect how the AF system performs.

If you want to use the D300(S) as a point-and-shoot camera,
center the AF point rectangle in the
lock on L. Once locked, the camera will only use the center
AF point in Single-point AF
