(1) Flash with Aperture-Priority AE

When you want to control the depth of field or when you want the

background correctly exposed, use aperture-priority AE. You set the

aperture and the camera sets the shutter speed automatically to suit the

background’s light level. The E-TTL auto flash system controls the flash

output according to the aperture you set.

Set the camera to

(aperture-

priority AE) and set the desired

aperture.

Check that the FP flash switch is
set to the green dot.

Press the shutter button halfway to

focus the subject.

Check that nothing is blinking in the
viewfinder and press the shutter

button completely to take the

picture.

In low-light conditions, a slow sync speed is set automatically. A tripod is
recommended for siow sync speeds.

1^ If the maximum sync speed blinks, the background will be overexposed. If the 30"
L|J sync speed blinks, the background will be underexposed. Change the aperture

setting until the sync speed stops blinking and stays on.
