Taking Photos in the Full Automatic Mode
There are two shutter release modes: “ S ”
(single-frame advance mode) and “ C ” (continu-
ous advance mode). (See page 46.)
When set to “
L ,” the power is turned off.
There are three focus modes: “ S ” (single focus
mode), “ C ” (continuous focus mode) and “ M ”
(manual focus mode).
1. Set the shutter release mode selector lever to “S”
(single-frame advance mode).
2. Set the focus mode selector lever to “S” (single
focus mode). (This control is located at the lower left
front of the camera.)
There are three exposure metering modes: “ A ”
in which the average light of the entire picture is
measured with emphasis on the center of the
picture, “
S ” in which the light in a spot at the
center of the picture is measured, and “ A-S ”
which combines these two to automatically
switch the mode according to the extent of
difference between the brightness of the light
metered in the two modes and sets the
distribution ratio of the exposure metering
modes within an intermediate range. (See
page 61 and 62.)
4. Set the exposure metering mode selector lever to
“A-S” (average/spot auto switching).
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).
Focus mode Focusing
Half-press the shutter release button to focus. When the focus mark
lights, the focus is fixed and the shutter can be released.
(See page 43.)
Focusing is performed continuously while the shutter release button
is half-pressed. The shutter can be released regardless of whether
or not the focus mark is lit. (See page 43.)
Focus manually. (See page 45.)

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 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.)
