USING THE MULTI(6)-SEGMENT METERING MODE
31
BASIC OPERA
TION (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.
