ABOUT THE F50/F50D METERING SYSTEM
The Nikon F501F50D has two types of exposure metering systems-Matrix Metering and Centre- Weighted Metering.
o
Matrix Metering
With D-type AF Nikkor lenses including AF-S/AF-JNikkor: 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 Al-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.
