Nikon Camera F50 - Manual (Page 14)

SEHING CAMERA TO AUTOFOCUS MODE
Autofocus should be used for most picture-taking
situations, including moving subjects. In general, it is
best to leave the focus switch set to AF.
» For situations where autofocus is not possible,
see page 44.
• For manual focusing, see page 45.
Regarding the F50/F50 d ’ s autofocus
feature
Your F50/F50D is factory-set to Single Servo AF
operation. This means that once your subject is
in focus, focus remains locked as long as the
shutter release button is lightly pressed. You can
recompose the picture, and the subject will
remain in focus, provided you maintain the same
subject-to-camera distance. (See page 41 for
details.) If the subject moves, take your finger
off the shutter release button, then lightly press it
again to restart autofocus operation.
• In the ADVANCED mode, in addition to
Single Servo AF, you can choose Continuous
Servo AF which keeps autofocus operation
going continuously as long as you keep lightly
pressing the shutter release button. (For details,
see page 34.) Use Continuous Servo AF for
sports and other action photography.
