EXPOSURE LOCK - AEL BUTTON
The AE lock button locks the automatic exposure system without activating the AF system. This
function allows the exposure to be set by a gray card or reference target outside the scene. When
using flash in the P or A exposure modes, slow-shutter sync is active (p. 47). The operation of the
AE lock button can be changed in section 1 of the custom menu (p. 95).
Frame the exposure target in the viewfinder depending on the metering mode in use
(p. 50). Press and hold the AE lock button (1) to lock the exposure; the shutter speed
and aperture are displayed and the AEL indicator is displayed in the viewfinder and
on the monitor. 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 and monitor Ev scale
shows the difference between the locked exposure and the current light level measured with the
meter. Spot metering is used.
When using flash, pressing the AEL button activates the
slow-sync. function in program, full-auto program, and
aperture priority. Slow sync. balances the ambient light
exposure with the flash exposure so the background is
recorded with the subject.
When the AEL button is pressed and held, the ambient
light exposure is determined and the flash exposure is
based on the locked aperture setting. The use of a tripod
is recommended with slow-sync. exposures.

AEL indicator Ev scale
2
When the Ev scale indicates 0, the locked exposure shown in the shutter-speed and aperture
displays is the same as the exposure determined by the spot-metering area.
The metered area is 1.0Ev less (–) than the locked exposure.
The arrow indicates the metered area is 0.5Ev more (+) or less
(–) than the greatest value on the scale in comparison to the
locked exposure.
The blinking arrow indicates the metered area is 1.0Ev or more
greater (+) or less (–) than the greatest value on the scale in
comparison to the locked exposure.
The increments on the scale depend on the exposure-compensation dial position. See camera
notes on page 41. The examples below are based on a 0.5 Ev increment.
