The Genustech Wide Matte Box Kit with Top Flag, Rod Adapter, and Step-Up Rings includes the GWMC Wide Angle Matte Box, GFF Top Flag and Top Flag Assembly, Rod support adapter, 82mm Lens Adapter Ring, and 82mm Filter Step-Up Ring Set. The GWMC Wide Angle Matte Box for 4 x 4" filters includes a wide-angle matte box with a 105mm attachment, a 4 x 4" rotating filter stage, and a 4 x 4" fixed filter stage. The rotating filter stage features click-stops at 90° of rotation. It comes with two 4 x 4" filter trays.
The kit includes an adapter that enables mounting the matte box onto 15 or 12mm support rods. This allows you to use the lens without mounting it on the front of your lens, which is useful if the front of your lens rotates when focusing. The included top flag assembly mounts on the matte box hood, and it allows attaching the included top flag as an eyebrow. The included Adapter Ring for Select Clip-On Matte Boxes threads into lenses with an 82mm threaded front, providing a 105mm diameter and allowing you to clamp the matte box onto the lens without the support. The 82mm Filter Step-Up Ring Set allows for the usage of 82mm filters and accessories on lenses with 52, 58, 62, 67, 72, and 77mm filter threads.
