The S (ISO Sensitivity) Button Hold the S button and rotate the main command dial to adjust the camera's sensitivity to light according to the amount of light available. The current setting is shown in the shooting display and control panel. Choose from settings of from ISO 64 to ISO 25600 (or in the case of the Z 6, of from ISO 100 to ISO 51200); settings of from about 0.3 to 1 EV below the lowest of these values and 0.3 to 2 EV above the highest are also available for special situations. b mode offers an additional ISO-A (auto) option. S button Main command dial D 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. D Hi 0.3-Hi 2 Hi 0.3 through Hi 2 correspond to ISO sensitivities 0.3-2 EV over the highest numerical value. Hi 0.3 is equivalent to ISO 32000 (Z 7) or 64000 (Z 6), Hi 2 to ISO 102400 (Z 7) or 204800 (Z 6). D Lo 0.3-Lo 1 Lo 0.3 through Lo 1 correspond to ISO sensitivities 0.3-1 EV below the lowest numerical value. Lo 0.3 is equivalent to ISO 50 (Z 7) or 80 (Z 6), Lo 1 to ISO 32 (Z 7) or 50 (Z 6). Use for larger apertures or slow shutter speeds when lighting is bright. Highlights may lose some detail; in most cases, ISO sensitivities at or above the lowest numerical value are recommended. 82 Shooting Controls
