DUCLOS CINE-MODS w/Metal Front Cap

1. Focus Gear
Duclos 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 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
New Optical Brilliance-designed Aluminum 80mm Front Caps include focal length, speed, series and close focusing distance all available 'at a glance.' This high quality cap fit snug and is composed of durable thermoplastic polymer with plated fronts for added protection.

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. They use a high-quality lubricant to ensure a professional feel and operation of your lens.

5. Duclos Canon EF/EOS mount
Duclos Lenses mount conversions 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.
