Metering
The process of measuring the brightness of the subject to determine the
exposure is known as “metering.”
Use this option to set the method of how the camera meters exposure.
1
When Focus-coupled metering is set to On and AF area mode ( E49) is set to
Manual, the brightness of the subject is measured by giving higher priority to the
focus area. See “Focus-coupled Metering” (
E58) for more information.

Can be used with focus lock ( A85) to meter off-center subjects.
