Taking Photographs—Exposure

Metering

In P, S, A, and M modes, the metering mode determines how the camera sets

exposure. The following options are available when a CPU lens is attached

(metering is not performed when a non-CPU lens is used).

Exposure

Controlling How the Camera Sets Exposure

Camera meters circle 2.3 mm (0.09˝) in diameter (approximately 1% of

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

meter off-center subjects (if Closest subjct is selected for AF-area mode,

camera will meter center focus area). En sures that sub ject will be cor-

rectly ex posed, even when back ground is much brighter or darker.

Spot

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

of frame 8 mm (0.31˝) in diameter, shown by corresponding 8-mm refer-

ence circle in viewﬁ nder. Classic meter for portraits; recommended when

using ﬁ lters with exposure factor (ﬁ lter factor) over 1 × ( 191).

Center-

weighted

DescriptionMethod

Metering is performed by 1,005-pixel RGB sensor, which sets exposure

based on variety of information from all areas of frame. This method is

particularly effective where frame is dominated by bright (white or yel-

low) or dark (black or dark green) colors, when its results approach what

is seen by human eyes. 3D color matrix metering, which uses range infor-

mation from lens in adjusting exposure, is available only with type G or D

lenses. Color matrix metering, which does not include range information,

is available with other CPU lenses. Matrix metering will not produce

desired results with autoexposure lock ( 84) or exposure compensation

( 86), but is recommended in most other cases.
