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.

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.
