The Copal No. 3 shutter is the largest in the standard Copal mechanical shutter series, featuring a generous 46.5mm aperture opening designed for large format lenses with substantial light-gathering capability. This precision leaf shutter maintains the reliable timing characteristics of smaller Copal units, offering speeds from 1 second to 1/500s, plus bulb and time modes. The No. 3 size is essential for wide-angle and fast telephoto lenses in large format photography, particularly those with maximum apertures of f/4.5 or larger. Its substantial construction and precise leaf mechanism ensure accurate exposure timing even with the increased mechanical demands of larger aperture control, making it indispensable for professional large format systems.
