Taking Photos in the Full Automatic Mode

1. Set the shutter release mode selector lever to "S"
(single-frame advance mode).

There are two shutter release modes: "S"
(singleframe advance mode) and "C"
(continuous advance mode). (See page 47.)
When set to "L", the power is turned off.

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 focus modes: "S" (single focus
mode), "C" (continuous focus mode) and "M"
(manual focus mode).

3. Set the exposure mode selector dial to "P" (program
auto exposure).

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

4. Set the exposure metering mode selector lever to
"A-S" (average/spot auto switching).

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 45.)
