The ARRI MB-19 Studio Matte Box is a compact, lightweight production mattebox. When mounted on the lightweight support LWS-3, graduated filters can be pushed through unhindered. Side flags with adjustable segments, used in conjunction with the top light shield, provide optimum protection against unwanted light.
The MB-19 is supplied with a filter stage for (2) 4″ x 5.65″ filters. The front filter can be pushed through vertically, and the rear filter can be displaced horizontally and additionally rotated. The filter stage is fitted with a rear receptacle for 138mm diameter filter rings as well as for an additional filter stage for one 4″ x 5.65″ filter and one 138mm round filter.
To simplify lens changing, the mattebox swings away from the console. For quick adaptation to different lens lengths, it can be moved forward and backward with a lockable adjustment knob.
