USING THE MULTI(6)-SEGMENT METERING MODE
31
BASIC OPERATION (SHOOTING)
In the multi(6)-segment metering mode, the meter-
ing system automatically measures light in six dif-
ferent zones, enabling proper exposure value in a
wide variety of normal and adverse lighting condi-
tions.
Set the metering mode switch to [ ].
The center-weighted metering mode and spot
metering mode are also available in this camera.
See page 55 and 56 for more details.
When the Adapter 645 for 67 lens or Helicoid
Extension Tube 645 attached, the center-weighted
metering mode is automatically set even if you
select the multi-segment metering mode. The
multi-segment mode cannot be used.
MULTI(6)-SEGMENT METERING
This camera incorporates a high-precision six-segment
TTL metering system. Light values are measured in six
segments within the image field, enabling an optimal
exposure to be made under a variety of lighting condi-
tions. With conventional averaged metering systems,
underexposure of the subject results from the brightness
of the background affecting the overall metering. With
multi(6)-segment metering, the camera records the bright-
ness in six zones within the image field and uses these
measurements to choose an exposure that will not under-
exposed the subject. The multi(6)-segment metering sys-
tem also calculates exposure values for a scene to auto-
matically compensate for high-contrast and other difficult
lighting conditions. Even a beginner can achieve excellent
results with ease.
