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, 5,
and A modes, from [ISO 64 - 100J (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.
In
M
mode, sensitivity will be locked at ISO 64.
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
(~ 6). If [Auto] is selected and the sensitivity is raised above ISO 64, the
g
icon will
be displayed (~ 31). When [Fixed range auto] is selected, the maximum value of
(H)
+
the sensitivity will be displayed.

Notes on ISO 3200
• When [3200] is selected for ISO sensitivity, image size is displayed in red during shooting.
• When [ISO sensitivity] is set to [3200], [Image size] cannot be set to
[~
4000x3000],
[~
3264x2448],
[E3
3984x2656],
[~
3968x2232], and
[~
2992x2992]. At these image size settings,
selecti:lg [3200] for [ISO sensitivity] automatically switches the [Image size] setting to
[~
2592x1944]. When any optiorl other then [3200J is next selected for [ISO sensitivity], the original
image size setting is restored.
• At an [ISO sensitivity] setting of [3200], the [Multi-shot 16J
(~
101) option of the continuous
shooting mode is not available. At a [Continuous] setting of [Multi-shot 16J, selecting [3200] for
[ISO senSitivity] switches the [Continuous] setting to [SingleJ. The [Continuous] setting does not
change even when [ISO sensitivity] is set to options other than [3200].

Note on Shutter Speed
When [1600], [2000], or [3200] is selected for [ISO sensitivity], the slowest shutter speed available is
down to 2 sec.
