The Vocas MB-255 Mattebox Kit with 77mm Adapter Ring helps control light and provides an efficient means for deploying and adjusting filters. MB-255 features a rear clamp with an inside diameter of 114 mm, which is ideal for mounting the matte box onto the Zeiss CP.2 line of cine lenses, and a 114 to 105 mm step-down adapter for attaching MB-2XX adapter rings. This kit also includes a step-down adapter ring which reduces from 105 mm to 77 mm, for mounting the matte box onto lenses with a smaller front side diameter.
For fine control over light, a french flag and internal eyebrows are standard features. The french flag mounts to the top of the matte box with Vocas's patented "heavy duty" French flag clamper. The internal eyebrows can be operated from the outside of the mattebox, allowing the user to adjust the matte to the zoom position of the lens.
