The Wooden Camera Zip Box Pro 4 x 5.65" Clamp-On Complete Matte Box Kit bundles the clamp-on matte box with a full set of eight interchangeable clamp-on backs — 114, 110, 104, 100, 95, 87, 85 and 80mm — so the same matte box can be moved across lenses of different front diameters simply by changing the back. It accepts up to three 4 x 5.65" (Panavision-style) filters without the need for filter trays. Lightweight yet durable, the kit ships complete with a carbon-fibre top flag.
