This listing is for a vintage Kern-Paillard Switar 50mm f/1.4 H16 RX cine lens. Made in Switzerland for the legendary Bolex H16 Reflex movie cameras, this lens is a classic piece of filmmaking history. The RX designation is crucial, as these lenses were specifically designed to correct for the optical aberration caused by the internal reflex viewing prism in Bolex H16 Reflex models, ensuring sharp, high-quality images.

Technical Specifications:

• Lens Mount: C-Mount (1" thread, 32 threads per inch).

• Focal Length: 50mm.

• Maximum Aperture: f/1.4.

• Minimum Aperture: f/16 or f/22 (depending on the specific version, as indicated by the image).

• Optical Design: This is a prime lens, known for its superb optical quality and fast aperture.

• Compatibility: This lens is a perfect match for Bolex H16 Reflex cameras. While it can be mounted on other C-mount cameras or adapted to modern mirrorless systems, the "RX" correction is specifically for the Bolex reflex prism.

Condition Report: The lens is in good cosmetic condition with some signs of use on the barrel. The focusing and aperture rings move smoothly. The glass is clear with no major scratches, fungus, or haze. The lens has a unique, mechanical depth of field indicator that fills with orange dots as you stop down, which appears to be functioning. The item comes with a front lens cap.
