ISO Setting

Adjust the camera’s sensitivity to light.

• Auto: The camera automatically adjusts sensitivity ac-

cording to brightness, the distance to the subject, and

the options selected for macro mode and picture qual-

ity and size.

• Auto-Hi (high sensitivity auto): As above, except that the cam-

era selects higher sensitivities when the subject is poor-

ly lit. The maximum sensitivity and the shutter speed to

shift the value of ISO sensitivity can be selected in the

setup menu (page 124).

• ISO 80–ISO 3200: Sensitivity is set to the selected value.

Note

• Step value for ISO sensitivity can be selected from 1EV or 1/3EV

in ISO Step Setting in the setup menu (page 124).

• “Noise” (random variations in brightness and color) may appear

in photographs taken at high sensitivities.

• The sensitivity displayed in the picture display in Auto and Auto-

Hi modes may differ from the actual value. If the flash is used,
a sensitivity of Auto is equivalent to ISO 154, regardless of the
value displayed in the picture display. The range of sensitivities
available in Auto mode when the flash is off is shown below:
