Large-Format 4x5.65 Matte Box (144mm)

Large-Format 4x5.65 Quick-Release Matte Box (144mm)

Vintage Cooke Zoom compatibility. We can create other custom sizes! Please contact! Built to handle your largest cinema zooms and wide  lenses, this 144mm native clamp-on matte box delivers pro-level light control without the massive weight penalty. It features our innovative quick-release filter mechanism, allowing operators to drop in filters instantly without holding up production or throwing off the rig's dynamic balance.

Engineered from ultra-light carbon-fiber polymer, it gives you dual-filter capacity and a massive 144mm native clamp, while the comprehensive adapter ring kit ensures it fits seamlessly on almost any lens in your kit.

Massive 144mm Native Clamp: Mounts directly onto large-diameter cine lenses, keeping your rig streamlined and bulk-free. Compatible with adapter rings. 

Rapid-Release Filter Clamp: Features a dual-action thumb screw. Adjust it to engage a spring-loaded lever for instant filter hot-swaps, or tighten it down fully to lock your filters during high-speed tracking shots.

Ultimate Lens Compatibility: The full kit includes an 7-ring step-down ecosystem (ranging from 135mm to 95mm), ensuring this single matte box works across your entire lens library.

Modular Top Flag: Features its own quick-release clamp. Instantly pop the flag off via a thumb screw, or remove the entire top flag assembly to strip the weight down even further.
