Auto Exposure Lock

To control the exposure of a specific area within a scene, measure the exposure for the area with Spot or Center-Weighted Metering, then press the AE/AF-L button to lock the exposure, and recompose the picture. Set exposure to a mode other than Manual.

1 While pressing the metering system selector lock release, rotate the metering system selector to select Center-Weighted or Spot Metering.

• When the AE/AF-L button is pressed, AE-Lappears in the viewfinder.
