Zenzanon PE lenses feature electronic flash synchronization to 1/500 seconds, which facilitates daylight fill-in flash at all shutter speeds. They offer 1/2 stop settings which allow precise exposure control. Seiko #0 shutters in each lens are controlled by an electronic timer in the camera body. This functional design guarantees shutter speed reliability no matter which lens is mounted on the camera.
