Tilta MB-T12-110 Matte Box Backing, 110mm Clamp-on Adapter

The Tilta MB-T12-110 is a clamp-on backing ring engineered for use with the Tilta MB-T12 matte box system. Its sole function is to provide the physical interface between the matte box and a lens with a 110mm front diameter, clamping securely around the lens barrel to hold the matte box in position. This eliminates the need for threaded filter rings and allows cinematographers and camera operators to attach or detach the matte box quickly during lens changes on set.

Because the MB-T12 matte box uses interchangeable backings to accommodate different lens sizes, the 110mm variant is one option within a range of available diameters. Shooters working with large-diameter cinema lenses — common in broadcast and high-end production environments — will find this backing necessary for proper matte box fitment. It is a straightforward, single-purpose component: there are no moving parts, electronics, or adjustments. Buyers should verify that their specific lens measures 110mm at the front before ordering, and note that the matte box body, filter trays, and other accessories are purchased separately.
