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.
The ISO speed is set automatically within ISO 100-400.
You can set the ISO speed to “
100
”, “
200
”, “
400
”, “
800
”, or “
1600
”. With

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