Shooting Controls
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.

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.
