The Chrosziel MB 450W Super Wide Matte Box is a lightweight, yet robust, carbon fiber matte box for professional video cameras. The "Super Wide" design allows for 1/3"-chip camcorders to use a wide 2.6mm focal length setting without vignetting. The 1/2"-chip camcorders can be used out to 3.6mm. Use the included top flag to control glare and reflections for improved contrast and reduced ghosting in the recorded image.
