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.
