CAMERA SENSITIVITY - ISO

ISO Auto
:move :sel. :enter
The auto setting automatically adjusts the camera sensitivity to the light conditions
between ISO 50 and 200. When any other setting than auto is used, "ISO" and the set
value is displayed on the monitors.
Photographers can select a specific sensitivity setting. 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 800 will have the most.
A change in ISO also affects the flash and shutter-speed range. See the next page for
more on the flash range, and page 55 for the shutter-speed range.
As the ISO value doubles, the camera sensitivity doubles; changing the ISO between 100
and 200, 200 and 400, or 400 and 800 changes the camera sensitivity by one stop or 1
Ev (p. 105). A change between 100 and 800 changes the camera sensitivity by a factor
of 8 or three stops. High ISO settings (400, 800) can allow the photographer to hand hold
the camera in low-light conditions without the need of a flash.

DVANCED RECORDING
Five settings can be selected for camera sensitivity: Auto,
50, 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 selected with the function button and
the controller (p. 64).
