Genustech DSLR Matte Box Kit with 37mm Adaptor Ring

The Genus DSLR Matte Box Kit with 46mm Adaptor Ring consists of a wide-angle matte box, two 4 x 4" filter trays (1 fixed and 1 rotating), GFFW French Flag, GMB/DSLR Adaptor Bar System, 1 GARD donut-style adaptor ring, 46mm step-down adaptor, and an adaptor unit to support 15mm and 12mm bars.

In addition to two 4 x 4" filter trays (1 fixed and 1 rotating), the Matte Box DSLR Kit also has a detachable GFFW French Flag that is made from high grade aluminum with a non-reflective black coating finish and can be adjusted using a lock knob to prevent light flare onto the camera lens. When not in use, the French flag can be folded down to act as a protective cover for the lens since it is the same size as the matte box.

Compatible with DSLR cameras such as Canon 5D mkII and 7D, the GMB/DSLR Adaptor Bar System with adjustable settings supports cameras and lens with different widths as well as accessories such as audio adaptors. The Donut-style adaptor ring ensures fit perfectly between the lens adaptor ring and the clamp ring of the matte box. In addition to the 46mm step-down adaptor to adjust to different lens fronts, the DSLR Matte Box has an adaptor unit to support 15mm and 12mm bars. Made from high-grade Delrin, the GARD donut-style adaptor ring is used to connect lens adaptor rings from 52-86 mm to the clamp ring of the matte box.
