The flash range is measured from the CCD. Because of the optical system, the flash
range is not the same at the lens’ wide-angle position as it is at the telephoto position.
CAMERA SENSITIVITY - ISO
FLASH RANGE AND CAMERA SENSITIVITY
Five camera sensitivity settings can be selected: Auto, 50,
100, 200, and 320; the numerical values are based on an
ISO equivalent. ISO is the standard used to indicate film
sensitivity: the higher the number, the more sensitive the
film. Camera sensitivity is set in section 3 of the P, A, S, and
M menus (p. 44).

The auto setting automatically adjusts the camera sensitivity to the light conditions
between ISO 50 and 160. When any other setting than auto is used, “ISO” and the set
value will be displayed on the monitor.
A specific sensitivity setting can be selected. As the ISO value doubles, the camera
sensitivity doubles. Like grain in silver-halide film that increases with speed, noise
increases with sensitivity in digital imaging; an ISO setting of 50 will have the least noise
and 320 will have the most. An ISO setting of 320 may allow the camera to be hand-held
in low-light conditions without the need of a flash.
