D|Focus Systems 86 to 82mm Step Down Ring

The D|Focus Systems 86 to 82mm Step Down Ring lets you attach the D/Matte Mattebox, which has an 86mm lens opening, to any lens with an 82mm filter diameter. The 86mm side snaps onto the mattebox and the 82mm screws onto a lens. To step down beyond 82mm, D/Focus Systems has 82mm-to-below rings, sold separately, that you can attach onto the 86-to-82mm ring.
