A The Shooting Menu ISO sensitivity can also be adjusted from the shooting menu. Choose ISO sensitivity settings to adjust settings for viewfinder and live view photography (0 290) and Movie settings > Movie ISO sensitivity settings to adjust settings for movie live view (0 64). A ISO Sensitivity The higher the ISO sensitivity, the less light needed to make an exposure, allowing faster shutter speeds or smaller apertures, but the more likely the image is to be affected by noise (randomly-spaced bright pixels, fog, or lines). Noise is particularly likely at settings between Hi 0.3 and Hi 2. A Hi 0.3-Hi 2 The settings Hi 0.3 through Hi 2 correspond to ISO sensitivities 0.3-2 EV over ISO 12800 (ISO 16000-51200 equivalent). A Lo 0.3-Lo 1 The settings Lo 0.3 through Lo 1 correspond to ISO sensitivities 0.3-1 EV below ISO 64 (ISO 50-32 equivalent). Use for larger apertures when lighting is bright. Contrast is slightly higher than normal; in most cases, ISO sensitivities of ISO 64 or above are recommended.
