Z

Metering determines how the camera sets exposure. The 
following options are available:

a

3D color 

matrix II

Recommended in most situations. Camera meters a wide 
area of the frame and sets exposure according to distribution 
of brightness, color, distance, and composition for natural 
results.

Z

Center-

weighted

Camera meters entire frame but 
assigns greatest weight to area in 
center of frame (defaults to 12-mm 
circle in center of viewfinder; if CPU 
lens is attached, area can be selected 
using Custom Setting b5, [Center-
weighted area], pg. 316

). Classic 

meter for portraits.

b

Spot

Camera meters circle 4 mm (0.16 in.) in 
diameter (approximately 1.5% of 
frame). Circle is centered on current 
focus point, making it possible to 
meter off-center subjects (if non-CPU 
lens is used or if auto-area AF is in 
effect (pg. 76), camera will meter 
center focus point). Ensures that 
subject will be correctly exposed, even 
when background is much brighter or darker.

1 When non-CPU lens is attached, average for entire frame will be used if 

[Average] is selected for Custom Setting b5; otherwise, center-weighted 
metering for non-CPU lenses will use 12-mm circle in center of viewfinder, 
regardless of setting selected for [Non-CPU lens data].

2 For improved precision with non-CPU lenses, specify lens focal length and 

maximum aperture in [Non-CPU lens data] menu (pg. 218).

3 Metered area is not actually displayed in viewfinder.
