Sensitivity (ISO Equivalency)
Sensitivity can be set higher than the default setting (ISO 200 equivalent) when
taking photographs in low light conditions. Four settings (ISO 200, 400, 800,
and 1,600 equivalent) are available.

Camera Settings: Sensitivity (ISO Equivalency)
The default setting of ISO 200 equivalent is recommended in most circumstances.
Photographs taken at other settings may include a slight amount of noise.
Sensitivity can be further increased by a factor of +1 or +2 over ISO 1600, making
fast shutter speeds possible when lighting is poor (see “Custom Settings,” item
31). Note that in this case photographs may display higher levels of noise. It is
recommended that you take a trial photograph and check the results before
shooting in this mode.
At a setting of +1, the sensitivity display in the rear control panel shows HI-1; at a
setting of +2, HI-2 is shown.
