Tilta MB-T12-134 Clamp-On Adapter 134mm

The Tilta MB-T12-134 Clamp-On Adapter (134 mm) is a precision-machined aluminum ring that allows secure clamping of the lightweight carbon-fiber Tilta MB-T12 45.65 matte box directly onto any lens with a 134 mm outer barrel. This essential accessory is designed for popular large-format primes and zooms, such as Laowa OOOM, certain Sigma FF High-Speed, and select anamorphics that require fast, light-tight clamp-on mounting.

Exclusively designed for the MB-T12 matte box, the MB-T12-134 adapter converts the matte box mounting from rods or 114 mm donut to a robust 134 mm clamp-on system. It easily slides into the matte box's keyhole slots and locks instantly with two captive thumbscrews, gripping the lens front via a large, glove-friendly rear thumbscrew. Constructed from CNC aluminum with stainless-steel hardware, it ensures perfect alignment, zero play, and no light leaks, making it ideal for cinematographers seeking speed and simplicity while using high-end 134 mm front lenses on the MB-T12 platform.
