The Tilta 4 x 5.65″ Carbon Fiber Matte Box easily mounts onto 19mm rails via its 19mm rod adapter. It features two 360° rotating aluminum filter holders of 4 x 5.65″. The lightweight carbon fiber construction adds very little weight to your system, and the swing-away design allows you to make quick lens changes and simply move the matte box away from your lens when you’re not using it without having to detach it from your system. For use with 15mm rod systems, a 15mm rod adapter is included.
The matte box also comes with 80, 90, 114, and 134mm lens adapters to fit most telephoto lenses, and three flags to reduce side flare.
