Exposure

Metering

Controls used: button + main command dial

The metering method determines how the camera sets exposure. The following options

are available:

Method Description

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.

Center-weighted

Camera meters entire frame but assigns greatest weight to center area.

Classic meter for portraits; recommended when using ﬁ lters with an expo-

sure factor (ﬁ lter factor) over 1 × (

122).

Spot

Camera meters circle 3.5 mm (0.14 in.) in diameter (approximately 2.5 % of

frame). Circle is centered on current focus area, making it possible to meter

oﬀ -center subjects (if non-CPU lens is used or if Auto-area AF is selected

for Custom Setting 2 (

87), camera will meter center focus area). Ensures

that subject will be correctly exposed, even when background is much

brighter or darker.

To choose a metering method, press the button and rotate the main command dial until

the desired mode is displayed.

12—Center Weight (

90)

This option controls the size of the area assigned the greatest weight in center-weighted metering.

The default is 8mm (0.31in.).

3D Color Matrix II Metering

In matrix metering, exposure is set using a 420-segment RGB sensor. Use a type G or D lens for results

that include range information (3D color matrix metering II; 117). With other CPU lenses, 3D range

information is not included (color matrix metering II).
