CAMERA SENSITIVITY (ISO) AND ZONE MATCHING
Sensitivity / Zone Matching
The auto setting automatically adjusts the camera sensitivity to the light conditions
between ISO 100 and 800, and ISO 100 and 400 when using flash. The fixed numerical
settings are based on the film ISO equivalent: the higher the number, the more sensitive.
As the ISO value doubles, the camera sensitivity doubles; a change of one Ev. Noise
increases with sensitivity; an ISO setting of 100 has the least noise and 3200 has the
most. Noise is a grainy texture that can be apparent in the image.
Zone Matching is used for recording high-key (Hi200) or low-key (Low80) scenes. The
number refers to the approximate ISO equivalent for reflected-light meter measurements.
A high-key scene is made up of predominately light tones and colors. A low-key scene is
made up of dark tones and colors. Zone Matching controls exposure and contrast to
improve reproduction of these scenes. When selected, the zone indicator is displayed in
the camera-sensitivity display on the monitor. Any changes to contrast with the Digital
Effects Control are canceled (p. 63).
