The Tilta MB-T15 is a compact and versatile matte box designed for follow focus in photography and filmmaking. With its clamp-on feature, the MB-T15 easily attaches to the top of a tripod or camera rig for added functionality. This model from Tilta is a top choice for professionals looking for a reliable and efficient solution for mini tripod heads. The box is open but the unit is unused none of the heads have been used. There is a slight nick on the front element see photo (this is how the unit came). The corners of the boxes are slightly pressed in (again this is how it came). Includes original instructions. See photos for condition.
