Manual Adjustment

The camera's sensitivity to light can be adjusted according to the
amount of light available. Choose from settings that range from
1
ISO 100 and ISO 25600 in steps equivalent to / EV. Settings of
3
from about 0.3 to 1 EV below ISO 100 and 0.3 to 4 EV above ISO
25600 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 panels or
viewfinder.
