Metered-value difference indicator

Keep pressing the AEL button and the difference between the metered exposure value and the exposure of the new composition will be displayed on the viewfinder LCD. This function can be used to see if an object of very different brightness levels can be properly photographed.

If the difference between the set value and the metered value exceeds 6EV, the viewfinder LCD blinks “– u –” for underexposure and “– o – ” for overexposure.

By turning the front or rear dial in the AE lock mode, you can change the aperture and shutter speed value without changing the exposure value that is set when entered into AE lock mode.

In the “P” mode (Program AE) mode, turning either the front or rear dial shifts the program to “PH” and “PL.” When in “Av” (Aperture-priority AE) or “Tv” Shutterpriority AE), turning one of the dials changes both the aperture and shutter speed values.
