P: Program AE - The aperture and shutter speed are determined automatically according to the shooting conditions. This mode is best suited for general photography, since it allows you to concentrate on the shooting. You can change the shutter speed and aperture by turning

the front and rear dials while the “P” (Program AE) mode is selected.

Av: Aperture priority AE - Set the desired aperture and the camera selects the correct shutter speed. Use this mode to control depth of field.

Tv: Shutter priority AE - Set the desired shutter speed and the camera selects the correct aperture. Use this mode to stop motion.

M: Manual mode - Set this mode when you want to use special combinations of the aperture and shutter speed.

4.Exposure metering mode is automatically set to average/spot exposure metering before exposure metering is performed.

There are three exposure metering modes: In the “A” mode the average brightness in the entire frame is measured with emphasis on the center of the frame. The brightness at a specific spot in the center of the frame is metered in the “S” mode. The “A-S” mode automatically switches between these two modes depending on the contrasts in the picture.

NOTE:

When a polarizing filter is used, ensure that a circular polarizing filter(C-PL) is used. The correct exposure cannot be obtained with a normal(linear) polarizing filter (PL).
