X ISO Sensitivity
Raising the ISO sensitivity reduces the amount of light needed to make an
exposure, allowing pictures to be taken in low light conditions. A higher sensitivity
also allows for faster shutter speeds, reducing blur caused by subject movement
or camera shake.
• High ISO sensitivity settings are useful when taking pictures in dim lighting,
when shooting without a flash, or when using the telephoto setting, but they
may also produce “noise” -- randomly spaced, brightly colored pixels -- in the
dark areas of images.

Notes on ISO Sensitivity
• There are functions with which this setting cannot be enabled. See “Features That Cannot Be
Applied Simultaneously” ( A 64) for more information.
• When the ISO sensitivity setting is set to any option other than Auto, motion detection (A 29) is
disabled.

Option Description
s Auto (default setting)
Sensitivity is ISO 125 when there is sufficient lighting; the
camera compensates by raising sensitivity to a maximum of
ISO 800 when lighting is poor.
Fixed range auto
Limit the camera’s automatically adjusted ISO sensitivity range
to between ISO 125 and ISO 400. By limiting the ISO sensitivity
to a maximum of 400, this option moderates the amount of
“grain” that appears in pictures.
