SmallRig VND filter for Revo-Arcane matte box

Rent a Rota Pola filter when you have a mattebox that doesn’t have a rotating tray for a standard polarizing filter.  This is basically a full 4×5.65 filter tray with a geared 138mm circular polarizer inside it.  This is the Tiffen Multi Rota Tray, but most people know it as a Rota Pola.  It fits the standard 6mm tray size (as in you pull out your matte box tray and replace it with this), which is also known as the Arri R2 standard thickness of tray.
