b4: Center-Weighted 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 set to 6, 8, 10, or 13 mm or to the average of the
entire frame.
Note that the diameter is fixed at 8 mm when a non-CPU lens is used.

b5: Fine Tune Optimal Exposure

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
D
Fine-Tuning Exposure
Exposure fine tuning 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
(0 107) is preferred in most situations.

c: Timers/AE Lock

c1: Shutter-Release Button AE-L

At the default setting of Off, exposure only locks when the AE-L/
AF-L button is pressed. If On is selected, exposure will also lock
when the shutter-release button is pressed halfway.
