Clip your matte box onto lenses with different outer diameters using clamp-on rings. These rings have an outer diameter of 114mm with an inner diameter ranging from 80mm to 110mm.
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 staying lightweight.
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 while maintaining a complete light seal for the lens.
ENG 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.
