S SHUTTER SPEED PRIORITY AE
When you set the desired shutter speed, the camera will select the
appropriate aperture value for correct exposure. You can achieve stop
action effects by selecting a fast shutter speed, or give the feeling of motion
to a moving subject by selecting a slow shutter speed.
1
Set the Exposure Mode to the S position.
(The shutter speed value is illuminated in
green.)
2
Set the desired shutter speed by rotating
the Front Dial.
(The shutter speed value can be set in
1/3 stop increments from 30 seconds to
1/2000 seconds.)
3
Press the shutter button “half-way” to
verify the focus and take the picture.

Depending on the selected shutter speed, the camera automatically sets
the aperture in the following range.
Shutter Speed Aperture
30s ~ 1/1250s F2.8 ~ F16
1/1600s F4.0 ~ F16
1/2000s F5.6 ~ F16
WARNING !!

If the appropriate aperture value is beyond the range of the lens in use,
due to the subject being too bright or too dark, the aperture value
indicator will blink. If the subject is too bright, set the shutter speed to a
faster one, or if the subject is too dark, set the shutter speed to a slower
one, until the indicator stops blinking.
