This matte box has been redesigned to accommodate wide angle lenses as well as standard lenses.
The Genus Wide Angle Matte Boxholds your 4???x4" filters in the new Genus Wide Angle Filter Trays. The matte box features the new third stand-off for added stability without compromising on the rotating function of the second filter tray. The Genus matte box is not just for video cameras. It is the perfect companion for your DSLR . The Canon 5D or 7D and the Genus Matte Box work well together. Not all lenses are made to the same diameter, therefore a lens adaptor ring is required to attach your lens to a matte box.

Angled grooves on the outer circumference make sure that your adapter ring will slot snugly and securely into the donut ring. This adapter ring is for 82mm filter thread.
