E ISO Sensitivity
Sensitivity is a measure of how quickly the camera reacts to light. The higher the
sensitivity, the less light needed to make an exposure. Although a high ISO rating
is suited for taking pictures of subjects in action or in poor lighting, high sensitivity
is often associated with “noise” - randomly spaced, brightly colored pixels
concentrated in dark parts 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 29). When set to Fixed range auto, U and the upper limit
of the ISO sensitivity is displayed.

Auto (default setting)
Sensitivity is ISO 80 under normal conditions; when lighting is poor and the flash is
off, 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 (default setting), or ISO 80-800. The camera will not raise 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 will be locked at the specified value.
• When ISO sensitivity is locked, Motion detection (A 122) does not function.
