The Sogno is unusual for having its controls, including the shutter release, operated by the left hand. It produces an 18 mm x 24 mm image on standard 35 mm film loaded in a special cassette provided with the camera.

"The Ducati Sogno Model No. 1 was introduced in 1938 for producing 18 x 24 mm format on standard 35 mm film, which was reloaded into a special smaller cassette. The camera had a focal plane shutter with speeds from 1/20 to 1/500, it had a Galilean finder and a coupled rangefinder and was fitted with a Vitor f/3.5 35 mm lens. This lens produced an angle of 46°."
