3D Color Matrix II Metering
In matrix metering, exposure is set using a 1,005-segment RGB sensor.
Use a type G or D lens for results that include range information (3D color
matrix metering II; see page 352 for information on lens types). With other
CPU lenses, 3D range information is not included (color matrix metering
II). Color matrix metering is available when focal length and maximum
aperture of non-CPU lens are specified using [Non-CPU lens data] item in
setup menu (see page 197; center-weighted metering is used if focal
length or aperture is not specified).
