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 Mode Dial to the A position.
(The aperture value indicator is illuminated in
green.)
2
Select the desired aperture value by using
button.
(The aperture value can be set in 1/3 stop
increments from F4 to F11.)
3
Press the shutter button “half-way” to verify
the focus and take the picture.
• Depending on the selected aperture value, the camera automatically sets the
shutter speed in following range.
Aperture Shutter Speed
F4.0 ~ F5.0 15s ~ 1/1000s
F5.6 ~ F7.1 15s ~ 1/1250s
F8.0 ~ F9.0 15s ~ 1/1600s
F10 ~ F11 15s ~ 1/2000s
WARNING !!
•
When is shown on the color LCD monitor, camera shake may occur
(the shutter speed is set slower than 1/25). If this mark is displayed, please
use the flash (P.43, 44, 66) or a tripod.
•
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.
