Metering

Metering determines how the camera sets exposure.

The

following options are available:

Method Description
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 8-mm circle in center
of viewfinder; if CPU lens is attached,
area can be selected using Custom
Setting b5, [Center-weighted area],
pg.277).
Classic meter for portraits.1
b
Spot
Camera meters circle 3 mm (0.12 in.) in
diameter (approximately 2% 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. 64),
camera will meter center focus point).
Ensures that subject will be correctly
exposed, even when background is
much brighter or darker.1
1For improved precision with non-CPU lenses, specify lens focal length and
maximum aperture in [Non-CPU lens data] menu (pg. 197).
