USING
THE
MULTI(6)-SEGMENT
METERING
MODE
x
In the multi(6)-segment metering mode, the metering sys-
tem automatically measures light in six different zones,
enabling proper exposure value in a wide variety of normal
and adverse lighting conditions.
Set the metering mode switch to [ zz ].
* The center-weighted metering mode and spot metering
mode are also available in this camera. See page 50 and
51 for more details.
* When the Adapter 645 for 67 lens or Helicoid Extension
Tube 645 is attached, the center-weighted metering
mode is automatically set even if you select the multi-
segment metering mode. The multi-segment metering
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 conditions.
With conventional averaged metering systems, underex-
posure of the subject results from the brightness of the
background affecting the overall metering. With multi(6)-
segment metering, the camera records the brightness in
six zones within the image field and uses these measure-
ments to choose an exposure that will not underexposed
the subject. The multi(6)-segment metering system also
calculates exposure values for a scene to automatically
compensate for high-contrast and other difficult lighting
conditions. Even a beginner can achieve excellent results
with ease.
