ISO Sensitivity The camera's sensitivity to light can be adjusted according to the amount of light available. Choose from settings that range from ISO 100 to ISO 12800 in steps equivalent to 1/3 EV. Settings of from about 0.3 to 1 EV below ISO 100 and 0.3 to 2 EV above ISO 12800 are also available for special situations. Auto, scene, and special effect modes also offer an AUTO option, which allows the camera to set ISO sensitivity automatically in response to lighting conditions. The higher the ISO sensitivity, the less light needed to make an exposure, allowing higher shutter speeds or smaller apertures.
