Locking the Exposure Before Shooting (AE Lock)

AE Lock is a function that locks the exposure (brightness) prior to taking a
picture. Use this when the subject is too small to obtain a proper exposure
or is backlit.

• The exposure remains locked in the following situations.
• while the =/L button is pressed
• while the shutter release button is pressed halfway
• for twice the amount of the meter operating time (p.95)
• You will hear a beep when AE Lock is activated and deactivated. The beep
can be turned off. (p.206)
• AE Lock is not available in p mode.
• If you want to also lock the exposure when the focus is locked, set [5. AE-L
with AF Locked] of the [A Custom Setting 1] menu to [On].
• When a mode is set, if the shutter speed or aperture value is changed while
AE Lock is engaged, the combination of shutter speed and aperture value
changes while the exposure remains the same.
• When using a zoom lens whose maximum aperture varies depending on the
focal length, the combination of shutter speed and aperture value changes
depending on the zooming position even while AE Lock is engaged.
