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; settings of
from about 0.3 to 1EV below ISO 64 and
0.3 to 2EV above ISO 25600 are also
available for special situations. b mode
offers an additional ISO-A (auto) option.
The S (ISO Sensitivity) Button
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
The settings Hi 0.3 through Hi 2 correspond to ISO sensitivities 0.3–
2 EV over ISO 25600 (ISO 32000–102400 equivalent).
D Lo 0.3–Lo 1
The settings Lo 0.3 through Lo 1 correspond to ISO sensitivities 0.3–
1 EV below ISO 64 (ISO 50–32 equivalent). Use for larger apertures or
slow shutter speeds when lighting is bright. Highlights may lose some
detail; in most cases, ISO sensitivities of ISO 64 or above are
recommended.
