ISO Speed
NOTE This setting does not apply when recording video clips.
This setting adjusts the sensitivity of the camera to light. When ISO Speed is set to the default Auto setting, the camera selects the best ISO speed for the scene.
Lower ISO speeds will capture the best quality images with the least amount of grain (or noise), but result in slower shutter speeds. If taking a picture in low light conditions without a flash at ISO 100, you may want to use a tripod. In contrast, higher ISO numbers allow faster shutter speeds, and can be used when taking pictures in dark areas without a flash, or pictures of fast moving objects. Higher ISO speeds produce pictures with more grain (or noise) and, thus, can be of lower quality.
1In the Capture Menu (page 55), select ISO Speed.

buttons to highlight a setting.
3Press Menu/OK to save the setting and return to the Capture Menu.
If the setting is anything other than the default Auto setting, the number value for the setting will appear in the Live View screen.
Except in My Mode (page 52), the new setting remains in effect until it is changed again or until the camera is turned off. The ISO Speed setting resets to the default Auto setting when you turn the camera off.
