AE Lock

AE lock enables you to lock the exposure at a different place from the point of focus. After locking the exposure, you can recompose the shot while maintaining the desired exposure level. This feature is useful for backlit and spotlighted subjects.

AE lock works differently depending on the selected AF point and metering mode. For details, see “AE Lock Effects” (→p.165).
