ISO Sensitivity
The camera’s sensitivity to light can be adjusted according to the
amount of light available. Choose from settings that range from
ISO 64 to ISO 12800 in steps equivalent to
1 /
3
EV. Settings of from
about 0.3 to 1 EV below ISO 64 and 0.3 to 2 EV above ISO 12800
are also available for special situations. 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 S button and
rotating the main command
dial until the desired setting is
displayed in the control panel
or viewfinder.
