Color matrix

Metering is performed by a CCD sensor with 1,005 metering pixels
(67 vertical, 15 horizontal), which sets exposure based on a variety of
information from all areas of the frame. This system demonstrates its
effectiveness most dramatically where bright (white or yellow) or
dark (black or dark green) colors occupy most of the frame, when it
produces r esults approaching what is seen by the human eye. 3D
color matrix metering, which makes use of range information from
the lens when adjusting exposure, is only available when a type G or
D lens is used. When lenses of other types are attached, color matrix
metering is used. This setting is not recommended when using auto-
exposure lock or exposure compensation; use center-weighted or
spot metering instead.

Center-weighted

The camera measures light over the entir e frame, but assigns the
greatest weight to a circular area in the center of the frame 8 mm
(0.31˝) in diameter (use the 12 mm/0.47˝ circle in the center of the
viewfinder as a reference for center-weighted metering).

Spot

The camera measures light in a circle 4 mm (0.15˝) in diameter cen-
tered on the current focus area, occupying approximately two per-
cent of the frame. Spot metering is recommended for backlit sub-
jects, compositions that contains areas of high contrast, and other
occasions when you want to limit metering to an area about the size
of the focus brackets. Because metering is linked to the current focus
area, we recommend that you arrange your composition so that the
main subject falls in one of the focus areas and then select that focus
area using the multi selector. Note, however, that when closest-sub-
ject priority is used or a non-CPU lens attached, metering will be
performed in the center focus area only.
