1. Focus Gear 

Duclos Lenses seamless 32-pitch (0,8 module) focus gears are precision machined from solid Black Delrin®, tailored to each lens individually in-house to ensure a no-slip, non-binding reliable fit. Every gear is machined and installed by a skilled technician on an individual basis to ensure a lifetime of accurate operation. No zips, clips, or 3D prints from Duclos Lenses!

2. Front Ring

Duclos Lenses front rings thread directly into the existing filter threads of your lens and provide a common 80mm outside diameter surface for clamp-on accessories as well as a 77mm filter thread on each ring. Precision machined from billet 6061 aluminum and anodized black for a durable finish. Available sizes range from a mere 47mm all the way up to an 82mm Step-Down ring.

3. Front Cap 

Custom Optical Brilliance Designed metal front cap includes important info like focal length, speed, series and close focusing distance for each lens. Made from aluminum, it's engineered to absorb impact, and keep your lenses clean & safe. 

4. De-Click / Dampen

Aperture de-clicking is a vital part of the Cine-Mod. A true cinema lens features a step-less aperture that allows fine adjustment without "clicking" between f-stops. Duclos Lenses modifies the aperture movement by removing the "click" mechanism and damping the movement to create a consistent, creamy rotation. We use a high-quality lubricant to ensure a professional feel and operation of your lens.

5. Duclos Canon EF/EOS mount. 

The mount conversions that Duclos Lenses provides are made from billet stainless steel to provide a robust, reliable marriage between your lens and camera body. All mount conversions include parts, hardware, installation, and calibration. The installation is carried out by a skilled technician and properly collimated using specialized test equipment.
