Automatic Exposure Control
Automatic exposure is the most convenient way to shoot with
the Nikon F3AF, because it ailows you to concentrate fuiiy on
the subject without worrying about the exposure. By presetting
the aperture and iocking the shutter speed diai @ at A, the
camera automaticaiiy sets the proper stepless shutter speed
from 1/2000 to 8 sec. as soon as the shutter release button ®
is depressed halfway. To keep you fully informed, the shutter
speed is displayed via LCD in the viewfinder. Speeds between
1/2 and 1/2000 sec. are shown as a reciprocal of the actual
speed, for example 125 means 1/125 sec. Speeds between 1
and 8 seconds are signified by a - symbol appearing to the
.upper right of the number, for example 8" means 8 sec. To make
-8- indicates the subject is too dark and you ■
should use a larger aperture. If the correct
exposure is unobtainable even at maximum
aperture, use an electronic flash or other
supplementary illumination.
.
When making blank exposures with the shut-'
ter speed dial set at A or 1/125 sec. or above,
an 80 will appear until you reach frame one. ,
the display easy to read, intermediate speeds appear in the
display as a discrete shutter speed which is closest to the actual
speed. (For instance, 1/287 sec. might be the automatically
selected shutter speed in use, but 250 will be displayed.) The
LCD stays on for approx. 16 sec. after you remove your finger
from the shutter button.
Before shooting, check the exposure display.
Note:
The camera's effective metering range depends on the shutter
speed and aperture in use at a particular film speed. Please refer to
pp. 66-69 for more information.
