Metering
Metering determines how the camera sets exposure.
Option
Description
L
[
Matrix
metering
]
The camera meters a wide area of the frame and
sets exposure according to tone distribution,
color, composition, and distance for results close
to those seen by the naked eye.
M
[
Center-
weighted
metering
]
•
The camera assigns the greatest weight to the
center of the frame. It can be used with
subjects that dominate the composition, for
example.
•
Center-weighted metering is also
recommended when using filters with an
exposure factor (filter factor) over 1×.
•
The size of the area assigned the greatest
weight can be selected using Custom Setting
b3 [
Center-weighted area
].
N
[
Spot
metering
]
•
The camera meters a circle with a diameter of
4 mm/0.16 in. (equivalent to approximately
1.5% of the frame). This ensures that the
subject will be correctly exposed even when
the background is much brighter or darker.
•
The metered area is centered on the current
focus point. If auto-area AF (
66) is in effect,
the camera will instead meter the center focus
point.

[
Highlight-
weighted
metering
]
The camera assigns the greatest weight to
highlights. Use this option to reduce loss of
detail in highlights, for example when
photographing spotlit performers on stage.
