AE Lock
AE lock enables you to lock the exposure at a place other than the point of focus. After locking
the exposure, you can recompose the shot while maintaining the exposure level. This feature is
useful for backlit and spotlighted subjects.
● The effects of the AE lock depend on the focusing point and metering method selected.
