This setting adjusts the sensitivity of the camera to light. When ISO Speed is set to Auto, the camera selects the best ISO speed for the scene.
NOTE If the camera is in ACTION, LANDSCAPE, or VIDEO mode, the ISO Speed will always be set to Auto and the ISO option in the Capture menu will be grayed out.
Lower ISO speeds allow slower shutter speeds, and will capture the best quality pictures with the least amount of grain (or noise). 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 higher 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 40), select ISO Speed.
2In the ISO Speed menu, use the
buttons to highlight a setting.
3Press OK to save the setting and return to the Capture menu.
If the setting is anything other than the default setting of Auto, the number value for the setting will appear in the Live View screen.
The new setting remains in effect until it is changed again or until the camera is turned off (unless ISO Speed is checked in the Remembered Settings menu - see page 90).
