AE lock-Locking the exposure AEL The metered exposure value can be locked with the AEL button (AE lock). Use AE lock when you want a different exposure setting from the one that would normally apply under the current shooting conditions. Normally, pressing the shutter button halfway locks both AF (auto focus) and AE (automatic exposure), but you can lock the exposure alone by pressing AEL. When you lock the exposure, the metering mode (digital ESP metering, center weighted averaging metering or spot metering) selected in the menu is automatically applied. ~ "AEL METERING" (P. 124) Available modes P A S 1 Aim the camera toward the subject. 2 Hold down AEL. 6 ● The exposure is locked. ● is displayed in the viewfinder.
