6-28
Center-Weighted Metering
With approximately 65% of the meter’s sensitivity concentrated on the 8.4 mm-diameter
circle in the viewfinder and approximately 35% outside this circle, this meter is useful
when you want to base your 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 AE-L button.
Refer to “Using the Auto Exposure Lock Function” on page 7-4.
Spot Metering
Nearly 100% of the meter’s sensitivity is concentrated on the 2.5 mm-diameter circle
(approximately 1% of entire frame) in the center of the viewfinder. Use this meter for
extra-selective exposure control; experience is required to achieve optimum results.
