Controlling Exposure
More on Photography
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
conditions. Aperture varies in increments equivalent to
1
3 EV (
1
3 step); de-
pending on the zoom position you may be able to achieve apertures as large
as f/5 or as small as f/8.
If the selected aperture would result in the picture being under- or over-ex-
posed, the aperture display in the monitor 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 the maximum and minimum
values for the camera lens, adjusted for the current zoom setting. Higher f/-num-
bers (smaller apertures) can be achieved by zooming the camera in, lower f/-num-
bers (larger apertures) by zooming the camera out. Unless On is chosen for Zoom
options > Fixed aperture in the shooting menu ( 105), 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-highest setting for the current
zoom position.
