(4) Aperture-Priority AE

[PURPOSE]

In this mode, the aperture is set manually and the

camera chooses correct shutter speed for the
lighting conditions (the opposite of shutter-priority

AE). Use this mode for portraits, landscapes and

still-life photography where depth of field is an im
portant factor, (see p. 36)

[SETTING]

1) While pressing the shooting mode selector,

turn the electronic input dial until “Av” appears
in the display panel.

2) Remove your finger from the shooting mode

selector. At this point, the initial aperture set

ting is always 5.6 (f/5.6).

3) Turn the electronic input dial until the desired

aperture value appears.

Underexposure — The shutter speed of 30”

starts blinking. Turn the electronic input dial and
set a larger aperture until 30” stops blinking.

ONrSHcV

Overexposure—The shutter speed of 2000 with
the EOS 650 or 4000 with the EOS 620 starts
blinking. Turn the electronic input dial and set a

smaller aperture until the shutter speed stops
blinking.

When the automatically-set shutter speed

is too slow to hand’hold, the camera-shake
warning sounds. We recommend using a
tripod.
