The Wooden Camera Zip Box Pro 4 x 5.65" Matte Box in its 100mm clamp-on configuration mounts directly onto a lens with a 100mm front, via a 100mm clamp-on back. It accepts up to three 4 x 5.65" (Panavision-style) filters without the need for filter trays. Because the clamp-on back is interchangeable, the same matte box can be refitted with a different-diameter back to work on other lenses, or converted to a swing-away matte box. Lightweight yet durable, it ships complete with a carbon-fibre top flag.
