Sensitivity Settings (ISO
SETTING)
The ISO sensitivity indicates how sensitive to
light the film is. A greater value means higher
sensitivity. High sensitivity is suitable for
shooting an object in a dark place or moving
fast and suppresses blurring. However, the
images become rough.
A digital camera can automatically vary the
sensitivity (AUTO).
Usually use your camera in the AUTO mode.
ISO sensitivity can be selected from seven
levels (AUTO, ISO64, ISO100, ISO200,
ISO400, ISO800, and ISO1600).
In AUTO mode, the sensitivity is ISO160 with
flash or ISO125 without flash. The ISO sensi-
tivity can be set by using the ADJ. Button or
using the Shooting Menu.
• By default, your camera is set to OFF.
• When shooting in a dark place without
using the flash, raising the sensitivity
enables you to give a subject more bright-
ness.
• If you increase the ISO Sensitivity, it
becomes possible to shoot under low light
conditions, but your pictures may become
grainy. The higher the ISO Sensitivity, the
grainier your pictures are likely to become,
so it is necessary to exercise caution.
