The Copal No. 1 shutter is a larger precision leaf shutter designed for medium and large format lenses requiring a 34.6mm aperture opening. This mechanical shutter offers the same reliable timing range as its smaller siblings, from 1 second to 1/500s, plus bulb and time settings. The No. 1 size accommodates lenses with larger maximum apertures and longer focal lengths, making it essential for portrait lenses and normal focal lengths in large format systems. Its robust construction features multiple leaf blades for smooth, accurate operation, and like all Copal shutters, it became widely adopted by lens manufacturers worldwide for its consistent performance and ease of integration into professional optical systems.
