The Vocas MB-256 has been specifically designed for use with Zeiss CP.2 lenses. Therefore this matte box is compatible with lenses that have a front side diameter of up to 114 mm.
The matte box features a Quick-Lock mounting system that attaches directly to the front lens barrel. This matte box can also be attached to the camera with a 15 mm lightweight support or on top 15 mm rails. The MB-256 matte box is also compatible with the Vocas swing away bracket (0460-0600)
This matte box accommodates 3×3″ through 4×6″ filters and works with most wide angle lenses in both 4:3 and 16:9 aspect ratios. The Vocas MB-256 has one rotatable and one fixed 4″ wide filter tray and it also features a patented “heavy duty” French flag clamper.
Internal eyebrows are standard on the MB-256. They can be operated from the outside of the matte box. These patented internal French flags allow the user to adjust the matte (or mask) to the zoom position of the lens.
Although the MB-256 can be used as a clip-on matte box, we recommend the use of a barsadapter or swing away bracket and a MBS-100 matte box support.
