Abstract
An exposure display device for a single lens reflex camera including light display elements for displaying either shutter speed or diaphragm value is disclosed. Nominal values representing either shutter speed or diaphragm value are marked on a glass plate disposed in the vicinity of the focusing plate of the camera's viewfinder. A first display section, comprising a first set of light display elements aligned with (and, if desired, located inbetween) the nominal values, creates a first exposure component (e.g. diaphragm value or shutter speed) display whose value is related to predetermined exposure conditions, such as object brightness, film sensitivity and the other exposure component (e.g. shutter speed or diaphragm value). A second display section, comprising a second set of light display elements, also aligned with the nominal values, creates a second display of the exposure component chosen to be displayed. The second display represents the actual position of the camera element controlling the displayed exposure component.
