The Arri MB-14 Production Mattebox is equipped with a 4-stage filter assembly for four 6.6 x 6.6 inch push-through filters that are rotatable in pairs.
Two of the filter frames are toothed for operation by knob or flexible shaft.
The 4-stage filter assembly has a rear receptacle for 6 inch, 138mm or 40 inch filter rings, for anti-reflection rings and additional 4 x 4 inch filter stage.
The 4 x 4 inch filter stage can be interchanged with other filter stages. (See "Specifications" tab for maximum filter combinations.)
For easy lens changing the mattebox swings open 90 degrees to the front. The lateral adjustment on the side of the mattebox is equipped with a quck-set clamp. A holder for secure mounting of French flags is included.
