AE Lock (AEL) Photography
AEL photography is used to make selective exposure measurements on
areas of your subject that are not in the center of the frame.
1. Set the Shutter Speed Dial to its ‘AEL’ position.
2. Look through the Viewfinder and position the most important part of your subject in the Viewfinder’s
center circle.
3. Depress the Shutter Release Button halfway and keep the button in this position. The exposure
information will be memorized as long as the button is held in position.
4. Recompose and focus your subject, and then fully depress the Shutter Release Button to activate the
shutter.
