Locking the Exposure Before Shooting (AE 
Lock)
• 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.97)
• You will hear a beep when AE Lock is activated and deactivated. The beep 
can be turned off. (p.208)
• AE Lock is not available in p mode. 
• If you want to also lock the exposure when the focus is locked, set [4. 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.
