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- 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

You can set the ISO speed to “100”, “200”, “400”, “800”, or “1600”. With C.Fn-08 [ISO expansion] set to [1: On] (p.143), “H” (ISO 3200) can also be set.
