ABOUT THE F50/F50D METERING SYSTEM
The Nikon F50/F50D has two types of exposure
metering systems—Matrix Metering and Centre-
Weighted Metering.
Matrix Metering
With D-type AF Nikkor lenses including AF-S/AF-I Nikkor: When you
set a Program, or Shutter-Priority Auto or Aperture-Priority Auto
exposure mode, 3D Matrix Metering automatically activates. Even in
extremely complex lighting situations, the six-segment Matrix Meter
analyzes scene brightness and contrast, automatically adjusting
everything to ensure correct exposure. In addition, the microcomputer
built in the D-type AF Nikkor lens sends the information about camera-
to-subject distance, enabling the camera's microcomputer to perform more
precise exposure analysis.
If non-D-type AF Nikkor lens or AI-P Nikkor lens is used, Advanced
Matrix Metering is activated; although there is no information about
camera-to-subject distance, correct exposure is assured.
Centre-Weighted Metering
When you set Manual exposure
mode, the camera automatically
switches to Centre-Weighted
Metering. Centre-Weighted
Metering places special emphasis
on brightness within the 12mm-
diameter central area of the
viewfinder, and useful to base
exposure on a specific area of the
scene.
