The Arri MB-20 II Basic Module is the main basic unit of the Arri Matte Box System. The Basic module includes a sun shade, and will connect to the 2 or 3 filter stage. You must also have to have a filter stage, bellows adapter, a console bracket, and a support bracket.
The biggest differences between the MB-20 and the MB-20 II is in the attachment mechanism between the actual plastic matte box and frame, and the attachment hardware for the eyebrows and side flags.
