Setting the Shutter Speed

When you set the shutter speed in the shutter speed-
priority AE mode, the camera automatically selects
an aperture value to match the brightness. Faster
shutter speeds allow you to catch an instantaneous
image of a moving subject while slower speeds
create a flowing effect and allow you to shoot without
a flash in dark areas.
Adjust the shutter speed using the
when the image is underexposed (insufficient light)
or overexposed (too much light) and the correct
exposure cannot be obtained.

The nature of CCD image sensors is such that
noise in the recorded image increases at slow
shutter speeds. This camera, however, applies
special processing to images shot at shutter
speeds slower than 1.3 seconds to eliminate the
noise, thereby producing high-quality images.
Nevertheless, a certain amount of processing time
may be required before the next image can be shot.
The aperture value and shutter speed change
according to the zoom state as follows.
Aperture value
f/2.8 – f/5.0
*1
f/5.6 – f/8.0
f/3.1 – f/5.6
*2
f/6.3 – f/8.0
The fastest shutter speed for flash synchronization
is 1/250 second. The camera automatically resets
the shutter speed to 1/250 second if a faster speed
is selected.
