Nikon F4S - Autofocus Operation

Autofocus

Single Servo Autofocus (S)
In Single Servo Autofocus mode (S), the shutter cannot be re-
leased until the subject is in focus; once the subject is in focus,
the focus stays locked for as long as the shutter release button
is tightly pressed. |
Continuous Servo Autofocus (C)

shutter release button lightly pressed. The shutter release but-
ton can be fully depressed anytime, regardless of focus status,
except when film advance mode selector is set to Cr.
