Beyond Point-and-Shoot—Shooting-Mode Selection
A: Aperture-Priority Auto
In aperture-priority auto, you control aperture by rotating the command dial,
while the camera automatically adjusts shutter-speed in the range 8 s–
1
/
2300
s
to produce optimal exposure. Aperture varies in increments equivalent to
1
/
3
EV (
1
/
3
step).
Faster Shutter Speeds
For shutter speeds faster than
1
/
2000
s, choose an exposure mode of aperture-
priority auto, select a smaller aperture (larger f/-number), and zoom the cam-
era all the way out. If lighting is sufficient, shutter speeds of up to
1
/
2300
s can
be achieved.
Aperture and Zoom
The maximum and minimum values for aperture are the maximum and mini-
mum values for the camera lens, adjusted for the current zoom setting. Higher
f/-numbers (smaller apertures) can be achieved by zooming the camera in,
lower f/-numbers (larger apertures) by zooming the camera out. Unless On is
chosen for Fixed Aperture in the Zoom Options sub-menu ( 113), aper-
ture will change as the camera is zoomed in or out. If, for example, you
choose the second-highest aperture setting with the camera zoomed all the
way out, the camera will vary the f/-number to maintain aperture at the sec-
ond-highest setting for the current zoom position as you zoom the camera in.
