Vintage all-black optical viewfinder assembly for the SOM Berthiot Pan-Cinor 70 17.5–70mm f/2.4 zoom lens, used with 16mm motion picture cameras.

The viewfinder has been visually compared with a silver-finish assembly matching the original SOM Berthiot documentation. Both appear identical in dimensions, mounting configuration, image magnification, and viewing field.

The optics transmit a visible image, and the mounting collar rotates freely. The assembly has not been tested mounted to a lens, so exact compatibility and optical alignment are unverified.

Good vintage cosmetic condition with signs of age and previous use. Please review all photographs for condition and details.

Viewfinder assembly only. No lens, camera, or additional accessories included. Sold as pictured.
