Tilta 4×5.65 Carbon Fiber Matte Box (Clamp-on)

The Tilta MB-T12 is a lightweight carbon fiber clamp-on matte box for three 4×5.65″ filters. It clamps directly onto the front of a cinema lens, so it needs neither rods nor a rubber donut; the kit includes five clamp-on backings for 80, 95, 110, 114 and 134 mm, five hard mattes, a top flag against flare and a 15 mm LWS rod adapter for the times you would rather hang the matte box on the cage.

The Tilta 4×5.65 Carbon Fiber Matte Box (Clamp-on) is a matte box built for cinema lenses with standard front diameters: the backing clamps it straight onto the lens, with no rods and no donut, while it carries three rectangular 4×5.65″ filters and a top flag. The carbon body keeps the weight down, so the build stays light even with a full set of filters.

Three 4×5.65″ filters in trays

The rear of the matte box takes three 4×5.65″ filter trays — ND, polarizer and diffusion at once — and each tray slides out on its own, so a filter is swapped without taking the build apart. Three trays come in the box; more are sold separately. The carbon body with aluminum and stainless steel parts is built so that a matte box with a full set of filters loads neither the clamp on the lens nor the gimbal.

Clamps onto the lens, no rods needed

The backing screws to the rear of the matte box and tightens directly around the front of the lens; it replaces both rods and the rubber donut that would otherwise seal the gap. The kit includes five backings for 80, 95, 110, 114 and 134 mm; other diameters are sold separately. When you would rather hang the matte box on the cage — with heavier filters or lenses without a suitable front — the included adapter mounts it on a pair of 15 mm LWS rods.

Top flag and hard mattes against flare

The top French flag folds down and shades the lens from side light so no stray light lands on the filter glass. The front of the matte box takes five hard mattes for focal lengths of 16–20, 24–28, 32–35, 50–85 and 85–180 mm, which crop the field of view to what the lens actually sees and block the rest. Mattes and trays are held in the matte box by thumb screws, no tools needed.

The Tilta MB-T12 matte box family

The MB-T12 is sold as a full kit with five clamp-on backings, or as a version with a single backing matching your lens diameter (80, 85, 95, 110, 114 or 134 mm). Additional backings, 4×5.65″ filter trays, the carbon fiber top flag and the 15 mm LWS rod adapter are sold separately, so the matte box grows as lenses are added.
