The SHAPE 2-Stage 4 x 4″ Matte Box accepts lenses with up to a 100 mm front outside diameter. It mounts to 15 mm LWS rods and utilizes a swing-away design, which lets you perform quick lens changes without having to remove the matte box from your rods. You can adjust the height of the matte box in relation to the rods, which comes in handy when your lens center to rod center height is slightly off from the standard. Two rotating filter stages support the use of 4×4″ filters. The matte box comes with a top flag (eyebrow), side flags, four matte box donuts in 66, 72, 82, and 90 mm sizes, and elastic donut. The matte box also has a rear opening of 100 mm for lenses.
The included anti-reflection donuts prevent light behind the camera from reflecting off any filters in the matte box and degrading the image. Included with the matte box are anti-reflection donuts for lenses with a front outside diameter of 66, 72, 82, and 90 mm. The included elastic donut supports lenses with a front outside diameter between 66 and 90 mm, and it is especially useful with lenses that grow and shrink as you change focus or zoom. The side flags incorporate a hook design as a safety feature where they attach to the matte box. This helps prevent them from falling out of the matte box should the lockdown thumbscrew loosen accidentally. The swing-away bracket incorporates a height adjustment, enabling you to compensate a total of 0.65″ vertically. This allows you to use this matte box with a variety of camera/rod support combinations that may vary slightly from the industry standard 85 mm distance from LWS rod center to lens port center.
