Tilta MB-T12-136 Clamp-On Adapter 136mm

The Tilta MB-T12-136 Clamp-On Adapter (136 mm) is a precision aluminum ring that allows the lightweight carbon-fiber Tilta MB-T12 45.65 matte box to clamp directly onto lenses with a 136 mm outer barrel diameter. This is the go-to solution for large-format cinema primes and zooms such as ARRI Signature Primes, Zeiss Supreme Primes, Tokina Cinema Vista, and many anamorphics that require a rock-solid, light-tight connection without rods.

Designed exclusively for the MB-T12 matte box, the MB-T12-136 converts the matte box to a fast, tool-free 136 mm clamp-on system. It slides into the matte box's keyhole slots and locks with two captive thumbscrews, then grips the lens front securely via a large rear thumbscrew. CNC-machined aluminum with stainless-steel hardware guarantees perfect concentricity and a zero play-free fit, ensuring zero light leaks. Essential for owners of ultra-wide or high-end large-sensor glass who want the speed of clamp-on mounting with the premium build quality of the MB-T12 ecosystem.
