Setting the ISO Speed

The ISO speed is a numeric indication of the sensitivity to light. (→p.154)

A higher ISO speed number indicates a higher sensitivity to light. Therefore, a high ISO speed is suited for moving subjects or taking pictures in low-light conditions. However, the image will contain more noise to make it look coarse or grainy. On the other hand, a low ISO speed will make the image look finer, but it is not suited for freezing motion or shooting in low light.

The camera can be set to any of the following ISO speeds: ISO 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, or 1250.

3 s The new ISO speed will be set.

When higher ISO speed is set or the camera is used under higher temperature, more noise will appear in the image. In this case, image file size will grow and fewer images will be recorded on the CD card. Number of shots remaining can be confirmed on the top LCD panel. (→p.27)

•With C.Fn-08-1/2, you can display the ISO speed instead of the number of remaining shots. (→p.135)
