Metering

q Evaluative Metering

This is the camera’s standard metering mode suited for most 

subjects even under backlit conditions. After detecting the 

main subject’s position, brightness, background, front and 

back lighting, etc., the camera sets the proper exposure.

¡

During manual focusing, evaluative metering is based 

on the center AF point.

¡

If the subject brightness and background light level are 

very different (there is a strong backlight or spotlight), 

use partial metering <w> instead.

w Partial Metering

Effective when the background is much brighter than the 

subject due to backlighting, etc. Partial metering covers 

about 9% of the viewfinder area at the center. The area 

covered by partial metering is shown on the left.

e Centerweighted Average Metering

The metering is weighted at the center and then averaged 

for the entire scene.
