There are three exposure metering modes: In
the “A” mode the average brightness in the en-
tire 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. (See page 61.)

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

There are four exposure modes: “P” (program AE),
“Av” (aperture priority AE), “Tv” (shutter priority
AE) and “M” (manual mode).

3. Set the exposure mode selector dial to “P” (pro-
gram auto exposure).

Features

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. (See page 53 and 54.)

Set the desired aperture and the camera selects the correct shutter
speed. Use this mode to control depth of field. (See page 55.)

Set the desired shutter speed and the camera selects the correct
aperture. Use this mode to stop motion. (See page 56.)

Set this mode when you want to use special combinations of the aperture
and shutter speed. (See page 57 to 59.)
