picture. Use this when the subject is too small or backlit and a proper
exposure setting cannot be obtained.

• @ is displayed in the viewfinder while the AE lock is engaged. (p.26)
• The exposure remains in memory for twice as much time as the metering timer
after releasing the L button. The exposure remains locked as long as the
L button is kept pressed or the shutter release button is kept pressed halfway.
• You will hear a beep when the L button is pressed. The beep can be
turned off. (p.189)
• AE lock is not available when the exposure mode is B (Green), p (Bulb) or
M (Flash X-sync speed) mode.
• The combination of shutter speed and aperture value changes depending on
the zooming position even while the AE lock is engaged when using a zoom
lens for which maximum aperture varies depending on the focal length.
However, the exposure value does not change and the picture is taken at the
brightness level set by the AE lock.
• Exposure can be locked when focus is locked. Set in [AE-L with AF locked]
in the [A Custom Setting] menu. (p.135)
