This Nikkor 50mm lens has been modified by Duclos Lenses via their Cine-Mod™process making them more useable for motion picture applications. The Cine-Mod consist of three primary parts: A seamless 32-pitch (0.8 module) focus gear, an 80mm front ring with 77mm filter threads, and a de-clicked, damped aperture movement. This lens has both Nikon and EF mount options.

A standard lens with an ultra-bright f/1.4 aperture, which allows for fast, accurate shooting with available light. Excellent choice for when a shallow depth of field is desired. The optical design of this lens minimizes flare and chromatic aberration. The SWM (Silent Wave Motor) feature ensures fast and quiet focusing action, and the nine-blade rounded diaphragm makes out-of-focus elements blend smoothly to produce natural-looking, harmonious backgrounds.
