Abstract
An exposure indicator for a camera having an electrical shutter capable of taking pictures under both automatic exposure and manual exposure. The exposure indicator comprises a rotary shaft associated with a changeover switch which selectively activates a combination of a photometric circuit for automatic exposure and its associated first shutter drive and control circuit or another combination of photometric circuit for manual exposure and its associated second shutter drive and control circuit; a carrier slidable in response to a switching action of the rotary shaft; a display panel carried by the carrier and carrying a zero method index for manual exposure and also carrying a train of numerals indicative of exposure values for automatic exposure, said carrier operating to move the display panel into or out of the optical path of a viewfinder; and a meter pointer disposed in relation to the display panel and activated in accordance with the brightness of an object being photographed, thereby providing an indication of the exposure values of the electrical shutter within the field of the viewfinder during the time a picture is being taken under automatic exposure.
