13.2 Stopped-down Metering 13 EXPOSURE MODES[For this mode. the AE Power Winder FN or AE Motor Drive FN must be attachedto the camera and the lens set to the ”A” mark.]3. Aperture-priority AESet the lens to the desired aperture and the camera automatically selects the propershutter speed according to the lighting conditions. This AE mode is useful forportraiture and still photography such as landscapes where depth of field is of im-portance.[For this mode, the AE Finder FN must be attached to the camera and the shutterdial set to ”A”]13.2 Stopped-down MeteringStopped-down metering is necessary whenever you are using a non-FD lens, such asthe Reflex 500mm, which has a fixed aperture, the TS 35mm lens or any of the olderFL lenses. It is also necessary whenever you insert accessories which do not havea full-aperture signal pin, such as bellows or extension tubes, between the camerabody and lens. Stoppeddown metering is possible, though unnecessary, with an FDlens. For correct exposure, set an aperture smaller than f/2.8.For stopped-down metering, the lens diaphragm must be closed down (stoppeddown) to the working aperture. Since the diaphragm will open and close as youturn the lens’aperture ring, depth of field can be easily checked.1. Stopped-down (Fixed-index) MeteringSet an aperture and unlock the stop-down slide by pushing it in and then releasingit. Turn the shutter dial (or aperturering) until.the meter needle is in line with thestopped-down metering index.2. Stopped-down AESet an aperture and unlock the stop-down slide by pushing it in and then releasingit. The camera will automatically select the proper shutter speed for the lightingconditions.This AE mode is especially advantageous in such fields as photomacrography andphotomicrography.[For this mode, the AE Finder FN must be attached to the camera and the shutterdial on ”A.”]26
