11.2.3 Centre-weighted Light Metering
When Centre-weighted Light Metering is used, the image area is divided into a “center”
and a „periphery“. All 7 of the sensors are active, however their measurements are
weighted differently: the measurement of the central sensor contributes 50%, and the
measurements of the 6 outer sensors contribute the remaining 50 % with 8,33 % for
each sensor.
Set the selector switch S3 to the position “Centre-weighted Light Metering”. Focus the
camera onto the image scene that the part of the image on which the light metering is
based is in the central measuring area. Lock the exposure values and reposition the
camera (AE-Lock or B1 / first pressure point), then release the shutter.
The focus and exposure settings are applied to the image when the Release Button B1 is
pressed (second pressure point).
Centre-weighted Light Metering S3 is suitable when the exposure of the image is to be
adapted to a limited area in the centre of the image.
11.2.4 Integral Light Metering
With Integral Light Metering, the entire area of the photographic image is taken into
account for the light metering. The 6 outer sensors are active, and the measurement
results of each sensor are equally taken into consideration: the upper two sensor pairs
contribute 33,33 %; the lower sensors contribute 16,66 % each to the light metering of
the image.
Set the selector switch S3 to the position “Integral Light Metering”. If necessary, lock the
exposure values using the button AF-Lock B10 or the Release Button B1 (first pressure
point), and reposition the camera. Release the shutter.
Integral Light Metering is suitable for images with low scene contrasts and equal light
conditions over the entire image area. Integral Light Metering renders predictable results
and therefore offers a reliable basis for exposure compensation.
