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

Description
L
Matrix
: 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 
(
0 373), distance information (3D color matrix metering III; with 
other CPU lenses, camera uses color matrix metering III, 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 (
0 213); otherwise camera uses center-weighted metering.
M
Center-weighted
: 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 b5, Center-weighted area
if non-CPU lens is attached, area is 12 mm in diameter). Classic 
meter for portraits; recommended when using filters with an 
exposure factor (filter factor) over 1×.
*
N
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, 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 (
