Auto Exposure Lock
In Live View, press the AE-L button to lock EV in Automatic Exposure Modes (A, S, P).
In Manual Exposure Mode, press the button to lock the aperture and shutter speed
combination. This allows users to shift the aperture and shutter speed combination using the
scroll wheels without changing the exposure. AE lock is not supported in Full Auto Exposure
Mode.
When the AE-L button is pressed, light metering is locked to the current EV setting. The AE-L
icon appears to the left of the aperture value, indicating that the function is enabled. Press
the button again to unlock.
In the locked setting, the aperture and shutter speed become interlocked. Users can
choose a new aperture and shutter combination that still represents the same EV setting.
For example, if the shutter speed is set to 1/125s and the aperture to f/8 with AE-L enabled,
users can access new EV-equivalent combinations by toggling the front scroll wheel, such as
1/30s at f/16 or 1/500s at f/4.
In practice, position the metering area (for example, using spot metering) over an area
equivalent to a mid-grey area and lock it with the AE-L button. Then recompose the picture
with the metering area positioned over an area much brighter or darker while retaining the
original exposure setting and choose a new combination of aperture and shutter speed
settings.
