<2.Taking photographs with the AE lock>
AE lock allows you to hold a certain exposure value even if the light changes or the composition is altered. It allows you to customize exposure in autoexposure modes. Use it when the subject is lit from behind or when you want to take a series of photographs of a moving subject with a constant expo- sure.
This locks the exposure (AE lock)
Viewfinder
Metering mark
Point the camera so that the cen- ter of the viewfinder is on the
area for which the exposure is required, turn the main switch “ON” and select “AEL”. The exposure is then locked (AE lock).
When you want to set the exposure on a select area within the frame, set the center divided partial metering mode then lock the exposure.
See page 31 for setting details.
•When the exposure is locked, the metering mark in the viewfinder flashes.
•Set the AE lock mode while the display in the viewfinder is lit.
Reposition the camera for the desired composition, then take the pic- ture.
•When the exposure is locked, the exposure remains in the memory and photographs can be taken as many times as you want with the same exposure value. To save energy, the mark turns off after 16 seconds.
•In the continuous shooting mode (drive mode “C”) the exposure can be locked on a mov- ing subject so that it is possible to take multiple photographs with the same exposure regardless of changes in the background.
•When AE Lock is set the camera stores the exposure determined by the combination of the shutter speed and aperture. In the “Av” mode, if the aperture is changed after the exposure is locked, the shutter speed is shifted so that the overall exposure remains con- stant.
•If the position of the exposure compensation dial is changed while the exposure is locked, the exposure compensation changes, depending on the exposure mode, as shown below.
