The Genus Wide 4x4 Matte Box Kit, bundled by B&H, suits both DSLR and video cameras, both wide-angle and standard lenses. This kit contains a 4x4" wide-angle matte box with a 105mm attachment, two 4x4" filter trays (one fixed, one rotating), a wide-angle ray shade, and a donut adapter ring for stepping down from the matte box to the kit's included 52mm lens adapter ring.
The Genus 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 tray, a 4 x 4" fixed filter tray, and a wide-angle rayshade. Standard lenses as well as wide-angle lenses can be accommodated using the wide rayshade.
Two lockable 4 x 4" filter holders are provided; one fixed and the other 360°-rotatable for graduating filters. Also included is an 82mm adapter ring, as well as a clamp ring that supports lenses and wide-angle adapters with diameters up to 105mm. A GARD donut adapter ring allows you to achieve a secure fit between the lens adapter ring and clamp ring of the matte box. You can use the matte box with 58 to 86mm lenses via screw-in adapter rings.
You can use the matte box with 12 or 15mm rods via an optional adapter unit. Weighing just 11.9 ounces, the Wide-Angle Matte Box is portable and provides an ideal solution for location-based shoots. You can use the matte box with camcorders and DSLRs such as the Canon 5D or 7D.
This Genus Adapter Ring for Select Clip-On Matte Boxes threads into lenses with 52mm threaded front, providing a 93mm diameter clamping surface for your Genus Matte Box Lite or Genus Wide Matte Box. Please note that this is not a filter-retaining ring. It is designed to mate your lens with a Genus Matte Box Lite or Genus Wide Clip-On Matte Box. It is made from anodized aluminum for strength and durability, and recommended for use with a lens that does not have a rotating front.
