Setting the Exposure for Shooting (A, B, C, D Modes)
More on Shooting
C (Aperture-Priority Auto) Mode
The user chooses the aperture value; the camera selects the shutter speed
automatically.
1
Rotate the mode dial to C.
2
Rotate the rotary multi selector to
choose the aperture value
(f/-number).
•
The aperture value can be set in a range of
f/1.8 to 8 (wide-angle position) and f/4.9 to
7.8 (telephoto position).
3
Focus and shoot.
• In the default setting, the camera automatically selects
one or more of the nine focus areas containing the
subject closest to the camera. When the subject is in
focus, the focus area (active focus area) lights in green
(maximum of nine areas) (A83).
B Note on C (Aperture-Priority Auto) Shooting
When the subject is too dark or too bright, it may not be possible to obtain the appropriate exposure
with the set aperture value. In such cases, the aperture value indicator blinks when the shutter-release
button is pressed halfway. Choose another aperture value and try again.
C Shutter Speed
• When the aperture value is set to f/1.8 (large aperture) or f/8, the shutter speed can be set to up to
1/1600 second.
• The control range of the shutter speed differs depending on the ISO sensitivity setting. Additionally,
the range is restricted during continuous shooting (A91).
D Aperture and Zoom
The aperture value (f-number) indicates the lens brightness. Large apertures (expressed by small f-
numbers) let more light into the camera, and small apertures (large f-numbers) let less light. When the
camera is zoomed in, the lens aperture can be changed within a range of f/1.8 to 4.9. The aperture
value increases (becomes darker) when zooming to the telephoto side, and decreases (becomes
brighter) when zooming to the wide-angle position.
