DVANCED OPERATION
AE LOCK BUTTON
The AE-lock button locks the exposure without activating the AF
system. This allows the exposure to be set with a gray card or a
reference target outside the scene. The operation of the AE-lock
button can be changed with custom function 9 (p. 70). This button
is disabled in shutter-priority and manual-exposure modes.
Frame the exposure target in the viewfinder
depending on the metering mode in use (p. 58).
Press the AEL button (1) to lock the exposure; the
shutter speed and aperture are displayed and the
AEL indicator is displayed in the viewfinder.
Release the button to cancel the lock.

While holding the AEL button, place
the subject in the focus frame and
press the shutter-release button
partway down to focus (2). Press the
shutter-release button down all the
way to take the picture.
The exposure remains locked after the picture is taken if the AEL
button is not released.
While the exposure is locked, the camera meter is still active. The
viewfinder Ev scale shows the difference between the locked
exposure and the current light level measured with the meter.
