s : Convey the Subject’s Movement
To freeze the motion of a fast-moving subject
Use a fast shutter speed such as 1/4000 sec. to 1/500 sec.
To blur a running child or animal and convey an impression of
motion
Use a medium shutter speed such as 1/250 sec. to 1/30 sec. Follow
the moving subject through the viewfinder and press the shutter
button to take the picture. If you use a telephoto lens, hold it steady
to prevent camera shake.
To blur a flowing river or fountain
Use a slow shutter speed of 1/30 sec. or slower. Use a tripod to
prevent hand-held camera shake.
Set the shutter speed so that the aperture display does not blink.
If you press the shutter button halfway and change
the shutter speed while the aperture is displayed,
the aperture display will also change to maintain the
same exposure (amount of light reaching the image
sensor). If you exceed the adjustable aperture
range, the aperture display will blink to indicate that
the standard exposure cannot be obtained.
If the exposure will be too dark, the maximum aperture (smallest
number) will blink. If this happens, turn the <6> dial to the left to
set a slower shutter speed or increase the ISO speed.
If the exposure will be too bright, the minimum aperture (highest
number) will blink. If this happens, turn the <6> dial to the right to
set a faster shutter speed or decrease the ISO speed.
To obtain a correct flash exposure, the flash output will be set
automatically (autoflash exposure) to match the automatically-set
aperture. The shutter speed can be set from 1/200 sec. to 30 sec.
