Exposure Metering
The Konica Hexar RF meters for exposure either by aperture priority auto-exposure (with AE lock and +/-2EV exposure compensation) or in metered-manual mode. Aperture priority is selected by setting the shutter speed dial to either the AE or AE lock position. Manual exposure is set by selecting a specific shutter speed on the shutter speed dial (there is a central interlock button to prevent accidentally moving the dial from the AE modes to a manually selected shutter speed).
Exposure metering is through-the-lens (TTL) and thus accounts for the aperture set on the lens in use. (Unlike SLR lenses, where the diaphragm controlling lens aperture is generally closed only at the time of shutter release, rangefinder camera lenses close or open the diaphragm directly as the aperture control is applied).
