This is a specialized and highly sought-after lens for 16mm filmmaking: the Kern-Paillard SWITAR 10mm f/1.6 Manufactured in Switzerland, this ultra-wide angle prime is specifically marked H16 RX on the barrel, indicating that it is optically corrected for use on Bolex H16 Reflex cameras (to account for the light path split by the reflex prism). This compensation is critical for achieving sharp focus when using the camera's viewfinder.

The 10mm focal length provides an extreme wide-angle field of view for the 16mm format. Its fast f/1.6 maximum aperture ensures excellent light gathering capability. The lens features the robust metal construction and precision engineering typical of Kern-Paillard optics.

This lens is an essential component for any filmmaker or collector operating a Bolex H16 Reflex body, and it can also be adapted for creative use on modern mirrorless cameras (with vignetting on larger sensors).
