ISO sensitivity The higher the ISO value, the greater the camera's light sensitivity and the better its ability to shoot in low light conditions. However, higher values also introduce electrical noise into the resulting image, which may give them a grainy appearance. AUTO : Sensitivity is automatically adjusted according to the light conditions and the subject brightness. 64/100/200/400: With a lower ISO setting, you can shoot clear, sharp images in daylight. With a higher ISO setting, you can use faster shutter speeds with the same amount of light.

Note The scale is approximate. • When ISO is set to AUTO and you are shooting in dark conditions without a flash, the sensitivity automatically increases, otherwise the shutter speed will be reduced, possibly resulting in camera movement and blurred images. • If the subject is too far away for the flash illumination to reach when ISO is set to AUTO, the sensitivity is automatically increased. • When using slow synchronization in the P, A or S mode, the slowest available shutter speed varies depending on the ISO setting. 130
