EXPOSURE COMPENSATION

compensation value. Then, release the Exposure
Compensation button.
The LCD panel will show “ 0.0” when you initially press the exposure
compensation button. The “ ” indicates overexposure, and “ ” indicates
underexposure.
Exposure compensation can be set in 0.5EV increments from +3.0 to –3.0 stops.

Aperture Priority mode. In Shutter Speed Priority mode, the aperture will be
one-stop larger (smaller F-number). In the case of Program mode, the shutter
speed will be 0.5 stop slower and the aperture will increase 0.5 stop.

Once you set the Exposure Compensation, the camera will continuously hold this
mode, until the compensation amount is set to
0.0 value.

Exposure compensation function cannot be used with Manual Operation mode.
