ISO Sensitivity
“ISO sensitivity” is the digital equivalent of film speed. Choose from settings that
range from a value roughly equivalent to ISO 100 to one roughly equivalent to ISO
6400 in steps equivalent to
1 /
3
EV. For special situations, ISO sensitivity can be raised
above ISO 6400 by from about 0.3 EV (Hi 0.3, equivalent to ISO 8000) to about 2 EV
(Hi 2, equivalent to ISO 25600). Auto and scene modes also offer an AUTO option,
which allows the camera to set ISO sensitivity automatically in response to lighting
conditions. The higher the ISO sensitivity, the less light needed to make an exposure,
allowing higher shutter speeds or smaller apertures.
ISO sensitivity can be adjusted by
pressing the ISO button and rotating the
main command dial until the desired
setting is displayed in the control panel
or viewfinder.
