Step 4—Focus
In single-servo AF, the camera focuses on the sub-
ject in the selected focus area when the shutter-
release button is pressed halfway. After centering
the focus brackets on your subject, press the shut-
ter-release button halfway and check focus in the
viewfinder. If the subject is dark, the AF-assist il-
luminator will light automatically to assist with the autofocus operation.
The Function Dial
Pictures can only be taken when the function dial is set to P, S, A, or M. At other
settings, the shutter release will be disabled.
Viewfinder Frame Coverage
Approximately 95% of the image exposed on the CCD is visible through the viewfinder.
The view through the viewfinder shows slightly less than appears in the final photo-
graph.
