[. . . ] The Aperture-Priority AE Mode does not operate unless the AE Pentaprism Finder 672 is attached. [. . . ] When the lens is stopped down, the exposure metering mode is set to Center-Weighted Metering Mode even if the metering mode selector is set to Multi (6)-Segment Metering Mode. 36 BASIC OPERATION [SHOOTING] Multi (6)-Segment Metering This camera incorporates a highprecision six-segment TTL metering system. Light values are measured in six segments within the image field, enabling an optimal exposure to be made under a variety of lighting conditions. With conventional averaged metering systems, underexposure of the subject results from the brightness of the background affecting the overall metering. With multi (6)-segment metering, the camera records the brightness in six zones within the image field and uses these measurements to choose an exposure that will not underexpose the subject.
