USING THE MULTI(6)-SEGMENT METERING MODE

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.
