E ISO Sensitivity
The higher the sensitivity, the less light is needed to expose an image, allowing
capturing darker subjects.
Also, a higher sensitivity allows higher shutter speeds, resulting in the picture with
less camera shake and subject blur in comparison to the same subject taken under
the same brightness.
Although high ISO sensitivity settings are suited to pictures of subjects taken
under dim lighting, those taken without flash, or those taken at telephoto
setting, high sensitivity settings are often associated with “noise”- randomly
spaced, brightly colored pixels- concentrated in dark portions of images.
B Notes on ISO Sensitivity
There are functions with which this setting cannot be enabled. See “Camera Settings that Cannot
Be Applied Simultaneously” (A78) for more information.
When the ISO sensitivity setting is set to any option other than Auto, Motion detection (A155)
is disabled.

s Auto (default setting)
Sensitivity is ISO 80 under normal conditions; when lighting is poor, the camera
compensates by raising sensitivity to a maximum of ISO 1600.
Fixed range auto
Choose the range in which the camera automatically adjusts ISO sensitivity, from
ISO 80-400 or ISO 80-800. The camera will not increase sensitivity beyond the
maximum value in the selected range. Set the maximum value for ISO sensitivity for
effective control over the amount of “grain” that appears in images.
80, 100, 200, 400, 800, 1600, 3200
Sensitivity is locked at the specified value.
