The ARRI MB-20 is a production matte box for 4 × 5.65″ filters with two filter stages – the rear one slides and rotates and has a holder for 138 mm round filters. It mounts on 15 or 19 mm rods.
It is light enough for a handheld camera and covers wide-angle zooms such as the Fujinon 4.5–13 mm. A third stage is optionally available; the 5.65 × 5.65″ filter overhangs top and bottom for large graduated filters.
