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.
At the settings other than Auto, the current setting is displayed in the monitor
(A 6). If Auto is selected and the sensitivity is raised above ISO 80, the E icon
will be displayed (A 32). When Fixed range auto is selected, U and the
maximum value of ISO sensitivity is displayed.
B Notes on ISO sensitivity
• There are functions with which this setting cannot be enabled. See “Camera Settings that Cannot
Be Applied Simultaneously” (A 51) for more information.
• Motion detection (A 145) does not function when the ISO sensitivity is locked.

Auto (default setting)
Sensitivity is ISO 80 when there is sufficient lighting, the camera compensates by
raising sensitivity to a maximum of ISO 1600 when lighting is dim.
Fixed range auto
Choose the range in which the camera automatically adjusts ISO sensitivity, from
ISO 80-400 (default setting) or ISO 80-800. The camera will not increase sensitivity
beyond the maximum value in the selected range. Specify the maximum 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.
