Auto-area AF
Auto-area AF turns the D300(S) into an expensive
point-and-shoot camera. Use this mode when you simply
have no time to think and would still like to get great images.
The AF Module decides what the subject is and selects the

for a period of one second. If, however, you are using
Continuous-servo AF (C) focus mode, nothing will appear on
the Viewfinder screen to give you a clue of what is going to
be in focus. In Auto-area AF, your camera operates like a
very expensive Nikon Coolpix point-and-shoot camera!

subject that is closest to the camera is the most-likely subject
anyway. Using Continuous-servo (C), your D300(S) can
