Changing the Sensitivity (ISO SETTING)
ISO sensitivity indicates how sensitive film is to light. A greater value
means higher sensitivity. High sensitivity is suitable for shooting an
object in a dark place or a fast-moving object while minimizing
blurring. However, the images become grainy.
You can choose from the following six ISO settings:
AUTO, ISO 64, ISO 100, ISO 200, ISO 400, and ISO 800.
When ISO setting is set to [AUTO], the camera automatically changes the
sensitivity according to the distance, brightness, zoom, and macro settings.
Usually, use the camera in the [AUTO] mode.
If you do not want to allow the camera to change the ISO sensitivity,
select an ISO setting other than [AUTO].

Press the C/D button.
The Shooting Setting menu is displayed.
3.
Press the " button to select [ISO
SETTING] and press the $ button.
4.

5.

6.
If you pressed the # button in Step
5, press also the C/D
button.
The ISO setting is completed.
The Shooting Setting menu closes and the
setting appears on the screen.
The setting is used for shooting until it is
changed.
Note
At the Wide-angle zoom setting, when the ISO setting is set to [AUTO], the sensitivity is
equivalent to ISO 160 with flash or ISO 100 without flash.
