The Proaim Camera Sunshade Matte Box is a 15mm rod-mount matte box for lenses with 95mm or smaller outer diameter. It is height-adjustable on the rod clamp for different-sized lenses, and compatible with lenses that have a focal length of 35mm or longer. It includes removable top, bottom, and side flags. The frame and rod clamp are aluminum and the matte box is made of durable plastic.

Both 4 x 4" filter stages rotate a full 360°. One filter holder is for 4 x 4" filters and the second is for custom 4 x 4.56" filters, though it also supports 4 x 4" filters. Both rotate a full 360°. Included with the matte box is a fabric donut, or "Nun's Knickers", that keeps light from leaking around the lens to flare any filters you are using. Interchangeable aspect ratio masks help prevent extraneous light from entering the matte box and potentially flaring the lens.
