Featuring functions that protect your camera and enhance creativity, the MB-436 matte box is designed as a 4"x5.65" matte box with all the unique Vocas features, but at an economical price. It is perfectly compatible with large lenses and the latest large sensor and 3D cameras. When the filter holders need to rotate above standard 15 mm rods, it is recommended to use a rotating bracket for this matte box. This will lower the rod height so that the filter holders can rotate freely.
