Autoexposure Lock
Exposure lock is used to recompose photographs after metering
exposure. It is most effective when used with center-weighted or
spot metering (0117) to frame off-center subjects that are
much brighter or darker than their surroundings or to optimize
exposure for an object other than your main subject.
1Meter exposure.
Position the subject in the center of
the frame and press the shutter-
release button halfway to meter expo-
sure. Check that the focus area is dis-
played in green.
2Lock exposure.
With the shutter-release button
pressed halfway and the subject posi-
tioned in the focus area, press 1 (A)
to lock exposure. While exposure lock
is in effect, an AE-L indicator will be dis-
played. Exposure will remain locked
while 1 (A) is pressed, even if you
later remove your finger from the
shutter-release button.
3Recompose the photograph.
Keeping the 1 (A) button pressed, recompose the photo-
graph and shoot. The option selected for Metering can not
be changed while exposure lock is in effect.
