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.

In the <1> (Full Auto) mode, the ISO speed will be set automatically within ISO 100-400.

At higher ISO speeds and higher ambient temperatures, the image will have more noise.

High temperatures, high ISO speeds, or long exposures may cause irregular colors in the image.
