Minolta F100 instruction manual Camera sensitivity ISO, Flash range and camera sensitivity

Camera sensitivity ISO

Five camera sensitivity settings can be selected: Auto, 100, 200, 400, and 800; 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 custom 1 section of the multi- function recording mode menu (p. 56).

The auto setting automatically adjusts the camera sensitivity to the light conditions between ISO 100 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.

A specific sensitivity setting can be selected. As the ISO value doubles, the camera sensitivity dou- bles. Like grain in silver-halide film that increases with speed, noise increases with sensitivity in digi- tal imaging; an ISO setting of 100 will have the least noise and 800 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)				Flash range (telephoto)
AUTO
	0.5m	~ 2.9m (1.6 ft. ~		9.5 ft.)	0.5m	~ 1.7m (1.6 ft. ~ 5.6 ft.)
100	0.5m	~ 2.0m	(1.6 ft. ~	6.6 ft.)	0.5m	~ 1.2m	(1.6 ft. ~ 3.9 ft.)
200	0.5m	~ 2.9m	(1.6 ft. ~	9.5 ft.)	0.5m	~ 1.7m	(1.6 ft. ~ 5.6 ft.)
400	0.5m	~ 4.1m	(1.6 ft. ~	13.5 ft.)	0.5m	~ 2.4m	(1.6 ft. ~ 7.9 ft.)
800	0.5m	~ 5.8m	(1.6 ft. ~	19.0 ft.)	0.5m	~ 3.4m	(1.6 ft. ~ 11.2 ft.)
