With approximately 75% of the meter’s sensitivity concentrated
on the 12mm-dia. circle within the viewfinder and 25% outside
this circle, this meter becomes useful in situations where you
want to base exposure on a specific area in the scene. In auto
exposure mode, to measure the brightness of the picture’s off-
center portion, use the camera’s AE-L/AF-L button (see pages
72 and 73).
Nearly 100% of the meter’s sensitivity is concentrated on the
4mm-dia. area (approx. 1.5% of entire frame) within the
selected focus area of the viewfinder. (6mm-dia. area or approx.
3.3% of entire frame with focusing screens other than EC-B/EC-
E-type.) Use this meter for highly selective exposure control—
achieving the best results requires experience.

In Center-Weighted Metering, the area
that concentrates 75% of the meter’s
sensitivity can be changed to 8mm-dia., 15mm-dia.,
20mm-dia. circle or average on entire viewfinder using
Custom Setting #14. See page 89.
When Spot Metering is selected, shifting focus area also
shifts Spot Metering area to corresponding position (with
EC-B/EC-E focusing screen only).
