gSetting the ISO SpeedN

The ISO speed is a numeric indication of the sensitivity to light. A higher ISO speed number indicates a higher sensitivity to light. Therefore, a high ISO speed is suited for low light and moving subjects. However, the image may look more coarse with noise, etc. On the other hand, a low ISO speed is not suited for low light or action shots, but the image will look cleaner.

The camera can be set between ISO 100 and 1600 in 1/3-stop increments.

ISO Speed in the Basic Zone Modes

The ISO speed is set automatically within ISO 100-400.

ISO Speed in the Creative Zone Modes

ISO 100-1600 can be set in 1/3-stop increments. With C.Fn-08 [ISO expansion] set to [1: On] (p.170), “H” (ISO 3200) can also be set.
