Metering

Choose how the camera sets exposure in P, S, A, and M modes (in other modes, the
camera selects the metering method automatically).
Option
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 (0 296), distance information (3D color matrix metering II; with
a 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.
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 b4, Center-
weighted area, 0 236; if non-CPU lens is attached, area is 8 mm in diameter). Classic
Z
meter for portraits; recommended when using filters with an exposure factor (filter
factor) over 1×.
Spot: 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
b
(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).
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.
