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 set to 8, 12, 15, or
20 mm or to the average of the entire frame.
Note that the diameter is fixed at 12 mm when a non-CPU lens is
used, regardless of the setting selected for Non-CPU lens data in
the setup menu (
0 163).
Use this option to fine-tune the exposure
value selected by the camera.
Exposure can
be fine-tuned separately for each metering
method by from +1 to –1 EV in steps of
1
/6 EV.

D Fine-Tuning Exposure
Exposure can be fine-tuned separately for each Custom Settings bank
and is not affected by two-button resets.
Note that as the exposure
compensation (E) icon is not displayed, the only way to determine how
much exposure has been altered is to view the amount in the fine-
tuning menu.
Exposure compensation (0 79) is preferred in most
situations.
