Four camera sensitivity settings can be selected with a still image: Auto, 50, 100, 200, 400; 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. Sensitivity can be changed in section
2 of the recording-mode menu (p. 43).
The auto setting automatically adjusts the camera sensitivity to the
light conditions between ISO 50 and ISO 160. When any other
setting than auto is used, “ISO” and the set value will appear on
the LCD 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 the sensitivity
in digital imaging; an ISO setting of 50 will have the least noise
and 400 will have the most.

Flash range and camera sensitivity
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.
