A APERTURE PRIORITY AE
After you set the aperture, the camera will determine the appropriate shutter
speed. If you select smaller apertures, depth of field will be greater. Larger
apertures tend to blur the background, as depth of field will be shallower.
1
Set the “D”-Dial to “Drive–Area” (P.14).
2
Set the “Mode” –Selector tothe A position
3
Press the shutter button “Half-Way” to verify
the focus, and select the desired aperture
value by turning the “C” –Dial.
4
Verify the setting in the viewfinder.
If the appropriate shutter speed is outside
the range of suitable combinations due to the
subject being too bright or too dark, the
shutter speed indicator will blink. If the
subject is too bright, set the aperture value to
a smaller one (larger F-number). If the
subject is too dark, set the aperture value to
a larger one (smaller F-number) until the
indicator stops blinking.
CAUTION!!
•
The range of available slow shutter speeds varies depending on the ISO setting
(P.52). At ISO 100 and 200, shutters speeds up to 15 sec. can be used. At ISO
400 and 800, shutter speeds up to 4 sec. can be used.

If extended mode is selected, you can take picture at 30sec. in any ISO settings
(see P.62）
