Metering

Choose how the camera sets exposure in P, S, A, and M modes (in other modes, the
camera selects the metering method automatically).
Method
Produces natural results in most situations. Camera uses 420-pixel RGB sensor
to meter a wide area of the frame and set exposure according to tone
L Matrix distribution, color, composition, and, with type G or D lenses (0 168), distance
information (3D color matrix metering II; with other CPU lenses, the camera uses
color matrix metering II, which does not include 3D distance information).
Camera meters entire frame but assigns greatest weight to center area. Classic
Center-
M meter for portraits; recommended when using filters with an exposure factor
weighted
(filter factor) over 1×.
Camera meters current focus point; use to meter off-center subjects (if e Auto-
area AF is selected for AF-area mode during viewfinder photography as
N Spot
described on page 58, camera will meter center focus point). Ensures that subject
will be correctly exposed, even when background is much brighter or darker.
