Minimise light leakage with our high-grade clamp rings. Made from top-quality Delrin plastic, these clamp rings allow for users to easily fit smaller lenses into standard-issue 114mm-diameter matte boxes. A Z-cut design ensures a tight hold, without light leaks; and the clamp ring sizes vary from 80mm up to 110mm: accommodating an array of lenses.
Ideal for quick lens-swapping and with ENG options for broadcasters, don’t miss out on these essential accessories.
Delrin Build
Rather than using plastic injection moulding, we choose to construct our rings from high-grade Delrin. This ensures dimensional accuracy and maximum clamping force, while retaining a light weight on the front of your camera.
Tightly Clamped
To protect the image from light leaks, all of our clamp-on rings feature our Z-cut design. This allows the ring to clamp tightly onto the lens with uniform pressure: ensuring a steady hold on your matte box.
Light-Sealed
The rings tightly lock the matte box in place, ensuring no light leaks escape around the edges of the lens.
Broadcast-Ready
The ENG variations of the clamp-on rings remove the front lip, which allows the matte box to slide further down on the lens.
Part of the Clamp-On Ring System
Our clamp-on rings are ideal for resizing the end of your lens for matte boxes and other accessories. For adjusting a variety of lenses to a variety of sizes, there are a number of alternate ring clamp sizes available:
143mm Clamp-On Rings
150mm Clamp-On Rings
