The Genus GL GMKBAS Basic Matte Box Kit with French Flag consists of the GWMC Wide Angle Matte Box and a GFFW French Flag.
Compatible with DSLR and Canon 5D cameras, the GWMC Wide Angle Matte Box accommodates up to two 4 x 4" filters and is equipped with an extra filter tray that offers stability when the second rotating filter is in use. The rayshade accommodates wide lenses and shields the camera lens from excessive sunlight. 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. The clamp ring allows you to connect lenses and wide angle adaptors with a diameter of up to 105mm
The Basic Matte Box Kit also has a detachable GFFW French Flag that is made from high-grade aluminum with a non-reflective black coating finish that 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 same size as the matte box.
