This is a classic French wide-angle cine optic: the SOM Berthiot CINOR D 15mm f/28. Manufactured in Paris, SOM Berthiot lenses are valued for their compact size and sharp, contrasty image rendering, making them a fixture in 16mm filmmaking.

The 15mm focal length provides a useful wide-angle perspective for the 16mm film format. The lens is built with the classic silver chrome and black enamel finish, featuring knurled rings for manual focus and aperture control.

The lens features the standard C-Mount screw thread, ensuring compatibility with classic 16mm cameras like Bolex and Bell & Howell, and making it easily adaptable to many modern mirrorless digital cameras for creative cinematic use.
