EISO 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 shooting 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.
Auto (default setting)
Sensitivity is ISO 64 under normal conditions; when lighting is poor and the flash is off, the camera compensates by raising sensitivity to a maximum of ISO 1000.
64, 100, 200, 400, 800, 1600, 2000
Sensitivity will be locked at the specified value.
At the settings other than [Auto], the current setting is displayed in the monitor
(A6). If [Auto] is selected and the sensitivity is raised above ISO 64, the Eicon will be displayed (A27).
