Choose how the camera sets exposure in P, S, A, and M modes (in other modes, the 
camera selects the metering method automatically).

To choose a metering option, 
press the Z (Q) button and 
rotate the main command dial 
until the desired setting is 
displayed in the control panel.

a

: Produces natural results in most situations. Camera meters a wide area of the 

frame and set exposure according to tone distribution, color, composition, and, with 
type G or D lenses (0 296), distance information (3D color matrix metering II; with 
other CPU lenses, camera uses color matrix metering II, which does not include 3D 
distance information). With non-CPU lenses, camera uses color matrix metering if focal 
length and maximum aperture are specified using Non-CPU lens data option in setup 
menu (0 150); otherwise camera uses center-weighted metering.

Z

: Camera meters entire frame but assigns greatest weight to center area 

(if CPU lens is attached, size of area can be selected using Custom Setting b4, Center-

weighted area, 0 236; if non-CPU lens is attached, area is 8 mm in diameter). Classic 
meter for portraits; recommended when using filters with an exposure factor (filter 
factor) over 1×.

*

b

: Camera meters circle 3.5 mm (0.14 in.) in diameter (approximately 2.5% 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, camera will meter center focus 
point). Ensures that subject will be correctly exposed, even when background is much 
brighter or darker.

*

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

aperture in Non-CPU lens data menu (0 150).

For information on making separate adjustments to optimal exposure for each metering 
method, see Custom Setting b5 (Fine-tune optimal exposure, 0 236).
