Custom Setting b6: Center Weight Area
When calculating exposure, center-weighted
metering assigns the greatest weight to a circle
in the center of the frame. The diameter (φ) of
this circle can be selected from 6, 8, 10, and
13 mm (the default option is 8 mm; note that the
diameter is fi xed at 8 mm when a non-CPU lens
is used, regardless of the setting selected for Non-CPU lens data in the
shooting menu, and that a setting of 13 mm is equivalent to 10 mm when
high-speed crop is on). Highlight b6 Center weight in the second level of
the CSM menu ( 180) and press the multi selector to the right. Press the
multi selector up or down to highlight an option, then press to the right to
make a selection.

Use this option to fi ne-tune the exposure value
selected by the camera. Exposure can be fi ne
tuned separately for each metering method by

right (select No to exit without altering exposure).
Press the multi selector up or down to highlight a

the right to display a list of exposure values. Press
the multi selector up or down to highlight an op-

Fine-Tuning Exposure
Exposure can be fi ne-tuned separately for each Custom Settings bank. Note that
as the exposure compensation icon ( ) is not displayed, the only way to determine
whether exposure has been altered is to view the fi ne-tuning menu. Exposure com-
pensation ( 99) is recommended in most situations.
