Shooting Options: The Shooting Menu E ISO Sensitivity Sensitivity is a measure of how quickly the camera reacts to light. The higher the sensitivity, the less light needed to make an exposure. Although a high ISO rating is suited for shooting pictures of subjects in action or in poor lighting, high sensitivity is often associated with "noise" - randomly spaced, brightly colored pixels concentrated in dark parts of the image. Auto (default setting) Sensitivity is ISO 64 under normal conditions; when lighting is poor and the flash is off, the camera compensates by raising sensitivity to a maximum of ISO 800. When a Speedlight (available separately from Nikon) is used with sensitivity set to [Auto], the maximum sensitivity applied is ISO 400. In M mode, sensitivity will be locked at ISO 64. Fixed range auto Choose the range in which the camera automatically adjusts ISO sensitivity, in P, S, and A modes, from [ISO 64 - 100] (default setting), [ISO 64 - 200], or [ISO 64 - 400]. The camera will not raise sensitivity beyond the maximum value in the selected range for effective control over the amount of "grain" that appears in images. 64, 100, 200, 400, 800, 1600, 2000, 3200 Sensitivity will be locked at the specified value. At the settings other than [Auto], the current setting is displayed in the monitor (A 6). If [Auto] is selected and the sensitivity is raised above ISO 64, the E icon will be displayed (A 31). When [Fixed range auto] is selected, the maximum value of P + the sensitivity will be displayed. Shooting, Playback and Setup Menus B Notes on ISO 3200 • When [3200] is selected for ISO sensitivity, image size is displayed in red during shooting. • [Image size] cannot be set to [F 4000×3000], [E 3264×2448], [I 3984×2656], [G 3968×2232], and [H 2992×2992] when [ISO sensitivity] is set to [3200]. If [ISO sensitivity] is set to [3200] while [Image size] is set to [F 4000×3000], [E 3264×2448], [I 3984×2656], [G 3968×2232], or [H 2992×2992], the [Image size] setting automatically switches to [D 2592×1944]. When any option other than [3200] is next selected for [ISO sensitivity], the original image size setting is restored. B Note on Shutter Speed When [1600], [2000], or [3200] is selected for [ISO sensitivity], the slowest shutter speed available is down to 2 sec. 99
