ISO Sensitivity
Sensitivity is a measure of the camera’s response to light. The higher the sensitivity,
the less light is needed to expose an image. Although high ISO sensitivity settings
are suited to pictures of moving subjects or those taken under dim lighting, high
sensitivity settings are often associated with “noise” - randomly spaced, brightly
colored pixels - concentrated in dark portions of the image.
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
31). When Fixed range auto is selected,
U
and the
maximum value of ISO sensitivity is displayed.

ISO sensitivity
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.
