Locking the Flash Exposure Setting (FE Lock)
You can lock the flash exposure so that the exposure settings are correctly set for a
particular portion of your subject. For an explanation of how different
combinations of light metering options and a selected AF frame affect where the
FE lock is metered, see page 80.

exposure setting.
Press the shutter button halfway.

While pressing the shutter button halfway, press the button.
The flash exposure compensation setting locks (FE lock) and the
icon
appears on the LCD monitor.
The flash will fire a pre-flash and lock the flash exposure to the required
intensity to illuminate the subject. (Each time you press the
button, the
flash exposure locks at the required intensity for that composition).
Using any button, lever or switch other than pressing the shutter button
halfway or using B, A, C or D on the multicontroller cancels the FE lock.

Recompose the image and shoot.
As the example to the right shows, a backlit
subject can be shot at the correct exposure if the
FE lock is set when the camera is aimed at a
non-backlit portion of the subject.
This function can only be selected in the , and shooting modes.
