4×5.65/138mm Rota Pola

4×5.65/138mm Rota Pola’s are a geared rotating filter tray that holds a 138mm circular polarizer within a standard 4×5.65″ cine matte box slot. This specialized tool allows cinematographers to rotate a polarizing filter even if their matte box does not have a built-in rotating stage, or when they need a secondary rotating stage for complex setups.

• Integrated Rotation: The 138mm round filter is mounted inside a rectangular tray. Built-in gears allow you to rotate the polarizer by spinning thumb wheels on either side of the tray without having to rotate the entire matte box.
• Variable ND Capability: When paired with a second fixed 4×5.65″ linear polarizer in another slot, the Rota Pola can function as a high-quality Variable Neutral Density (VND) filter.

Matte Box Compatibility: Designed for ARRI LMB-5, LMB-15, LMB-25 and LMB 4×5.

Available in ARRI, Tiffen, Revar Cine, Lentequip and Lindsey Optics.
