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 suitable 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.

ISO sensitivity

•Auto (default setting): Sensitivity is ISO 160 in bright places; in dark places the camera automatically raises sensitivity to a maximum of ISO 800.

•High ISO sensitivity auto: The ISO sensitivity is set automatically within the range of ISO 160 to 1600 according to the brightness of the subject.

•Fixed range auto: Choose the range in which the camera automatically adjusts ISO sensitivity, from ISO 160-200(default setting) or ISO 160-400. 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.

•160, 200, 400, 800, 1600, 3200: ISO sensitivity will be locked at the specified value.

Minimum shutter speed

When the shooting mode is Aor C and ISO sensitivity is set to Auto, High ISO sensitivity auto, or Fixed range auto, the shutter speed at which the ISO sensitivity automatic control starts to function (1/125 to one second) is set. The default setting is None. If the exposure is insufficient with the shutter speed that is set here, the ISO sensitivity is increased automatically to obtain the correct exposure. If the exposure is still insufficient even after the ISO sensitivity is increased, the shutter speed slows down.

At settings other than Auto, the current setting is displayed in the monitor (A8).

•If Auto is selected and the sensitivity is raised above ISO 160, the Eicon will be displayed (A36).

•Vis displayed when High ISO sensitivity auto is selected, and Uand the maximum ISO sensitivity value are displayed when Fixed range auto is selected.

CNotes on ISO Sensitivity

•In D (manual) mode, ISO sensitivity will be fixed at ISO 160 if Auto, High ISO sensitivity auto or Fixed range auto is selected.

•When the ISO sensitivity is ISO 800, the slowest shutter speed is restricted to four seconds, when ISO 1600, restricted to two seconds, and when ISO 3200, restricted to one second.

•This feature cannot be used simultaneously with certain features. See “Functions that Cannot be Applied Simultaneously” (A96) for more information.
