CAMERA SENSITIVITY - ISO
Five camera sensitivity settings can be selected: Auto, 64, 100, 200, and 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. Camera sensitivity is set in the basic section of the multi-function
recording mode menu (p. 50).
The auto setting automatically adjusts the camera sensitivity to the light conditions between ISO 64
and 320. When the flash is activated and camera sensitivity is set to auto, the ISO value is set
between ISO 64 and 200. When any other setting than auto is used, "ISO" will appear on the data
panel, and "ISO" and the set value will be displayed on the monitor.
Photographers can select a specific sensitivity setting. 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 64 will have the least noise and 400 will have the most
noise. An ISO setting of 400 will allow the camera to be hand-held in low-light conditions without the
need of a flash.
FLASH RANGE AND CAMERA SENSITIVITY
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.
ISO setting
Flash range (wide angle)
AUTO
0.5m ~ 3.5m (1.6 ft. ~ 11.5 ft.)
64
0.5m ~ 2.0m (1.6 ft. ~ 6.6 ft.)
100
0.5m ~ 2.5m (1.6 ft. ~ 8.2 ft.)
200
0.5m ~ 3.5m (1.6 ft. ~ 11.5 ft.)
400
0.5m ~ 5.0m (1.6 ft. ~ 16.4 ft.)
At the wide-angle lens position, when using the flash with subjects closer than 1m (3ft), vignetting
can occur. A slight shadow or shading may be apparent at the bottom of a horizontal image.
Flash range (telephoto)
0.9m ~ 3.0m (3.0 ft. ~ 9.8 ft.)
0.9m ~ 1.7m (3.0 ft. ~ 5.6 ft.)
0.9m ~ 2.1m (3.0 ft. ~ 6.9 ft.)
0.9m ~ 3.0m (3.0 ft. ~ 9.8 ft.)
0.9m ~ 4.2m (3.0 ft. ~ 13.8 ft.)
