Recording the Exposure Before Shooting (AE Lock)

 

AE Lock is a function that memorizes the exposure prior to taking the

5

picture. Use this when the subject is too small or backlit and a proper

exposure setting cannot be obtained.

 

Function Reference

1 Press the Lbutton.

The camera memorizes the exposure (brightness) at that instant.

Press it again to unlock.

@ is displayed in the viewfinder while the AE lock is engaged. (p.20)

The exposure remains in memory for twice as much time as the metering timer after releasing the Lbutton. The exposure remains locked as long as the Lbutton is kept pressed or the shutter release button is kept pressed halfway.

You will hear a beep when the Lbutton is pressed. The beep can be turned off. (p.170)

AE lock is not available when the exposure mode is a(Manual) or p(Bulb) 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.

If the exposure mode is a (Manual), the aperture and/or shutter speed are automatically adjusted to set the appropriate exposure when the L button is pressed. (p.146)

Exposure can be fixed when focus is locked. Set in [AE-L with AF locked] in the [ACustom Setting] menu. (p.131)
