AE Lock (AEL) Photography
The AEL position is very useful when making selective exposure measurements of important subject areas which are not in the center of the finder image when faced with difficult lighting conditions.
1. Align "AEL" on the shutter speed dial.
Rotate the shutter speed dial until "AEL" aligns with the white index mark on the camera body.
2.
Position the important part of your subject in the central square of the viewfinder
3. When changing composition.
In above state, the exposure reading will be memorized. After adjusting for composition as desired, release the shutter.
If you cannot get close enough to your subject for another meter reading make substitute measurements by pointing the camera to light and dark areas and calculate a mean exposure value or try taking a reading off your palm.
