Advanced Settings (M-REC): Metering Method
Metering Method
In determining autoexposure and shutter speed, the camera
uses one of three light-metering methods: matrix, spot, or
center-weighted. In
matrix
metering light is measured in sixty-
four different areas of the frame and exposure adjusted to a
level that in most conditions best captures both brightly-lit and
shaded portions of the image.
Spot
metering measures only
the light at the center of the frame. Where there is contrast
between different portions of the image, spot metering can be
used to throw a subject into high relief. When spot metering is
used, both focus and autoexposure settings will be locked when
the shutter-release button is half-pressed.
Center-weighted
metering measures the amount of light in the entire frame while
assigning the greatest weight to an area in the center of the
frame equal to one quarter of the total. Use this setting when
you would like autoexposure to be based on lighting conditions
in the center quarter of the frame.
To choose a metering method, highlight
METERING
in the
shooting menu and press the shutter-release button. The

Highlight the desired metering method and press the shutter
button. The current metering method is shown by an icon in
the control panel and shooting menu and, when the camera is

The chosen metering method is only valid when the camera is
in M-REC mode. If the selector dial is set to A-REC, matrix
metering will automatically be restored; the camera will how-
ever return to the chosen method when the dial is set back to
M-REC.
To return to the shooting menu without changing the metering
setting, highlight
BK
and press the shutter button. Pressing
the MENU button while in the metering menu will restore the
view through the lens without changing the metering method.
