The following optionsare available when the mode dial is rotated to P, S, A, or M (matrix metering is used in othermodes):Controls usedMeteringMetering is available with CPU lenses only. In matrix metering, exposure is set using a 420-pixel RGBsensor. Use a type G or D lens for results that include range information (3D color matrix metering II;97). With other CPU lenses, 3D range information is not included (color matrix metering II).CPU lenses can be identified by the presence of CPU contacts, type G and D lenses by a letter on thelens barrel. Type G lenses are not equipped with a lens aperture ring.CPU lens Type G lens Type D lens5—Metering ( 75)Metering can also be selected from the Custom Settings menu.Method DescriptionMatrixRecommended in most situations. Camera meters a wide area of the frameand instantly sets exposure according to distribution of brightness, color, dis-tance, and composition for natural results.Center-weighted Camera meters entire frame but assigns greatest weight to center area. Clas-sic meter for portraits.SpotCamera meters exposure in active focus area only (if Closest subject isselected for AF-area mode ( 24), camera will meter center focus area).Ensures that subject will be correctly exposed, even when background ismuch brighter or darker.
