Chrosziel GmbH Clamp-On Step-Down Ring for Cine.1 Matte Box 150 to 104mm
Clamps a Cine.1 matte box onto 104 mm cinema lenses with a secure, light-tight fit
- Clamp-on design enables fast matte-box changes on set
- 150 mm outer diameter fits Cine.1 Matte Box securely
- 104 mm inner diameter matches Schneider Cine Xenon and similar lenses
- Precision machining prevents vignetting and light leaks
- Durable construction maintains alignment during handheld or rigged shooting
Matte Box Adapter for 104 mm Lenses
The Chrosziel clamp-on step-down ring connects a Cine.1 matte box to cinema lenses with a 104 mm front diameter. It reduces the matte box opening from 150 mm to 104 mm for a secure, light-tight fit. Filmmakers using Schneider Cine Xenon or other 104 mm lenses gain a reliable attachment point for professional matte box workflows.
Check Lens Diameter and Matte Box Model
Verify that your lens has an external diameter of exactly 104 mm before ordering. Confirm you are using the Chrosziel Cine.1 matte box with a 150 mm clamping interface. The ring is designed solely for this specific combination and will not fit other matte box sizes or lens diameters.
Replaces Improvised Step-Down Solutions
This ring replaces makeshift adapters or tape-based workarounds that risk light leaks and vignetting. The precision-machined transition eliminates optical distortions caused by ill-fitting reducers. The upgrade is worth it when consistent, fast lens changes and clean image capture are required on professional productions.
