ISO Sensitivity
“ISO sensitivity” is the digital equivalent of film speed.
Choose from settings that
range from ISO 100 to ISO 6400 in steps equivalent to
1
/3 EV.
Settings of from about
0.3 to 1 EV below ISO 100 and 0.3 to 2 EV above ISO 6400 are also available for special
situations.
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 W (S) button and
rotating the main command dial until
the desired setting is displayed in the
control panel or viewfinder.
