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 AUTO If the mode dial is rotated to P, S, A, or M after AUTO is selected for ISO sensitivity in another mode, the ISO sensitivity last selected in P, S, A, or M mode will be restored. 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 100 (ISO 80-50 equivalent). Use for larger apertures when lighting is bright. Contrast is slightly higher than normal; in most cases, ISO sensitivities of ISO 100 or above are recommended. A The Shooting Menus ISO sensitivity can also be adjusted from the photo and movie shooting menus. Choose ISO sensitivity settings in photo shooting menu to adjust settings for viewfinder and live view photography (0 310) and Movie ISO sensitivity settings in the movie shooting menu to adjust settings for movie live view (0 322). A See Also For information on choosing the ISO sensitivity step size, see Custom Setting b1 (ISO sensitivity step value; 0 333). For information on adjusting ISO sensitivity without using the W (S) button, see Custom Setting d8 (Easy ISO; 0 341). For information on using the High ISO NR option in the shooting menus to reduce noise at high ISO sensitivities, see page 317. 135
