The Genus Special Matte Box Lite Kit consists of a lightweight clip-on matte box, a French flag, and three different-sized lens adapter rings.
The matte box comes with a universal adapter by which it clips onto camera lenses and with a filter tray that fits 4 x 4" filters. The French flag provides extra protection against flare and light penetration.
The adapter rings allow the matte-box to be attached to respective filter-thread lenses. The ring sizes are 67mm, 72mm, and 77mm.
