Use this option to set the method of how the camera meters exposure. Option G Matrix1 (default setting) Description The camera uses a wide area of the screen for metering. Recommended for typical shooting. The camera meters the entire frame but assigns greatest weight to the subject in the center of the frame. The q Center-weighted classic metering for portraits; it preserves background details while letting lighting conditions in the center of the frame determine exposure.2 r Spot1 The camera meters the area shown by the circle in the center of the frame. This can be used when the subject is much lighter or darker than the background. Ensure that the subject is within the area shown by the circle when shooting.2 1 When Focus-coupled metering is set to On and AF area mode (E49) is set to Manual, the brightness of the subject is measured by giving higher priority to the focus area. See "Focus-coupled Metering" (E58) for more information. 2 Can be used with focus lock (A85) to meter off-center subjects.
