Nikon 5400 사용자 설명서

When Manual is selected for AF area mode, fi ve 
focus areas are displayed in the monitor.  Press 
the multi selector up, down, left, or right to select 
the focus area containing your subject.  Manual 
focus area selection can be used in combination 
with focus lock (  29) if the subject does not fall 
in any of the fi ve focus areas.

Focus area selection (both manual and automatic) can be used in combina-
tion with spot AF-area metering to meter exposure only in the active focus 
area (  68).

In P, S, A, and M modes, the  Auto-focus mode 
option determines how the camera focuses when 
the monitor is on (single autofocus is used when 
the monitor is off, regardless of the setting cho-
sen for Auto-focus mode).

AUTO-FOCUS MODE

Single AF

Continuous AF

Camera adjusts focus continuously until shutter-release button is 
pressed halfway, minimizing time needed to focus before picture 
is taken.  Note that pictures can be taken even when camera is 
not in focus; check green (AF) lamp before shooting.

Camera focuses when shutter-release button is pressed halfway.  
If monitor is off, pictures can only be taken when camera is in 
focus.  Choose this option to save batteries.  Note that when 
monitor is on, pictures can be taken even if camera is not in fo-
cus; check green (AF) lamp before shooting.
