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. (See page 54.)
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). “ X ” is for
synchro mode, while “ CF ” is used to for custom
functions.
3. Set the exposure mode selector dial to “P”
(program auto exposure).
Exposure mode 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 44 and 45.)
Set the desired aperture and the camera selects the correct shutter
speed. Use this mode to control depth of field. (See page 46.)
Set the desired shutter speed and the camera selects the correct
aperture. Use this mode to stop motion. (See page 47.)
Set this mode when you want to use special combinations of the aperture
and shutter speed. (See page 48 to 51.)
