TIONS
The AE lock function enables an exposure level to
be memorized before shooting. The AE lock func-
tion is very effective when used along with spot
metering. Use the AE lock function to get a correct
exposure when the subject occupies only a small
part of the viewfinder.
Position the area to be measured in the spot
metering area and press the AE lock button. The
exposure level is memorized and [
] is dis-
played in the viewfinder.
• As soon as the AE lock button [ AE-L ] is pressed,
and the camera stores the measured exposure
level for 20 seconds. The AE lock function remains
while the AE lock button is depressed.
• If the shutter release button is depressed halfway
down while the AE lock timer is operating, the
memorized meter reading will remain even if the
AE lock button is released.
• The AE lock function cannot be used when the
camera is set in the Metered Manual Mode.
How to cancel
To cancel the AE lock function, press the AE lock
button again.
