Metering

Normally, the matrix metering system will provide the optimum exposure for your shot. However, you can choose from 3 metering modes for shots where you want to select a different exposure level (AE lock or exposure compensation) or for particular scenes (such as backlit shots or shots with very strong contrast).

Turn the metering selector to desired metering system.

Matrix metering

1,005-pixel RGB sensor sets exposure based on variety of information from all areas of frame. With type G or D lens, camera uses 3D color matrix metering II for natural results even when frame is dominated by bright (white or yellow) or dark (black or dark green) colors.

With other CPU lenses, 3D range information is not included; instead, camera uses color matrix metering II. Color matrix metering is available when a non-CPU lens is attached and if the focal length and maximum aperture of the lens are specified for [NON-CPU LENS DATA] under [ MISC.] in the [SET UP] menu (➝p.121; the center-weighted metering is used if focal length or aperture is not specified).

•For AE lock (➝p.69) or Exposure compensation (➝p.76), the Spot metering is recommended.

Center-weighted

Camera meters entire frame but assigns greatest weight to area in center of frame 8 mm (0.31 in.) in diameter, shown by corresponding 8-mm reference circle in viewfinder.

MEMO

The metering diameter can be changed by the [CENTER- WEIGHT AREA] setting under [SEXPOSURE] in the [SET UP] menu. Also, the average metering value of the entire frame is available (➝p.157).

Spot

Camera meters circle 3 mm (0.12 in.) in diameter (approximately 2.0% of frame). Ensures that subject will be correctly exposed, even when back ground is much brighter or darker.

•Circle is centered on current focus area (in group dynamic AF, on center focus area of current group; ➝p.56), making it possible to meter off-center subjects (if non-CPU lens is used or if dynamic-area AF with closest subject priority is in effect, camera will meter center focus area).

MEMO

• For improved precision with non-CPU lenses, specify lens focal length and maximum aperture in [NON-CPU LENS DATA] under [ MISC.] in the [SET UP] menu.

•When using non-CPU lens, center-weighted metering is used if focal length or aperture is not specified in [NON-

CPU LENS DATA] under [ MISC.] in the [SET UP] menu.

•Center-weighted is recommended when using filters with an exposure factor (filter factor) over 1x.
