Autoexposure Lock
Exposure lock is used to recompose photographs after metering
exposure. It is most effective when used with center-weighted
or spot metering (0128) 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.

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/AF-L indicator will be
displayed. Exposure will remain
locked until 1 (A) is pressed again,
even if you later remove your finger
from the shutter-release button.

Recompose the photograph and shoot. To end exposure lock,
press 1 (A) again.
Position the subject in the center of
