A: Aperture-Priority Auto
In aperture-priority auto, aperture is controlled by rotating the command dial;
shutter speed is set automatically by the camera in response to lighting condi-
tions. Aperture varies in increments equivalent to
1 /
3
EV ( 1 /
3
step); depending
on the zoom position, the camera can achieve apertures as large as f/2.8 or
as small as f/8.
Rotate command dial
until desired aperture ap-
pears in control panel and
shooting display.

If the selected aperture would result in the picture being under- or over-exposed,
the aperture display in the monitor or electronic viewfi nder will fl ash when the
shutter-release button is pressed halfway. Choose another aperture and try
again.
An aperture of f/8 may not be available at some zoom positions. For smaller
apertures, try zooming the camera out.
Aperture and Zoom
The maximum and minimum values for aperture are determined by the camera lens
and zoom setting. Unless On is chosen for Zoom options > Fixed aperture (
95),
aperture will change as the camera is zoomed in or out. If the second-highest aperture
setting is selected with the camera zoomed all the way out and the camera is then
zoomed in, the camera will vary the f/-number to maintain aperture at the second-high-
est setting for the current zoom position.
Faster Shutter Speeds
Depending on the amount of light available, it may be possible to achieve shutter
speeds as high as ¼
,000
s ( 1 /
8,000
s when shooting in Ultra HS) by zooming the camera all
the way out and selecting the smallest aperture (largest f/-number).
