Focusing Modes

When the Focusing Mode is Set to AF (auto focus)

If you set the focus mode selector switch to AF and hold the shutter button halfway, the camera automatically focuses on the subject and the focus indicator “●” appears in the viewfinder display to notify you that the camera has focused on the subject.

Auto AF servo (AF-A):

In this mode, the camera automatically determines whether the subject is moving and, if so, in which direction the subject is moving, and then selects either single AF servo (AF-S) or continuous AF servo (AF-C) accordingly.

Single AF Servo (AF-S):

The camera focuses on the subject and then fixes the focus (focus lock).

Continuous AF Servo (AF-C):

Focusing tracks the movements of the subject.

In either mode, the shutter does not release unless the focus indicator appears.

When you select Sport mode (5-vari program) as the exposure mode, focusing is set to continuous AF servo from the outset and focusing tracks the movements of the subject.

Auxiliary AF Light

0.5 - 3 m

(1.6 - 9.8 ft.)

If the subject is dark, the auxiliary AF light automatically switches on when the shutter button is pressed halfway to illuminate the subject and enable auto focusing. The auxiliary AF light operates under the following conditions:

1. When the focusing mode is AF, an AF Nikkor lens is mounted on the

camera and the subject is dark.

 

2.When an exposure mode other than Landscape mode or Sport mode is selected.
