Metering Systems

Since brightness and film sensitivity determine the proper combination of shutter speed and aperture for correct exposure, measuring subject brightness is very important.

The F6 provides three metering systems. With Matrix Metering (x 62), brightness data is detected using the 1,005-pixel Matrix sensor. With Center-Weighted Metering (x 63), brightness is detected in the central area of the viewfinder. With Spot Metering (x 63), sensitivity is concentrated in one of the 11 available focus areas.

Exposure

Light from the subject passes through the lens and exposes the film. Shutter speed and aperture control how much light reaches the film. The correct combination of shutter speed and aperture results in a correct exposure—a result provided by the F6’s four exposure modes: Programmed Auto, Shutter-Priority Auto, Aperture-Priority Auto and Manual.
