The CertoPhot is a vintage medium-format viewfinder camera introduced in East Germany around 1958. It uses 120 roll film to produce twelve 66cm square images. Its simple meniscus achromat lens is fixed-focus with two aperture settings (f/8 and f/11) and a single shutter speed at approximately 1/50s plus bulb mode. Zone focusing is done via a ring on the lens, ideal for distance guesswork. The all-metal body features classic styling, a reverse-telescopic viewfinder, film advance knob, red film window, tripod mount, cable-release socket, and flash sync
