Tiffen Multi Rota Tray Variable Neutral Density Kit with Extra 4x5.65" Circular Polarizer

The Tiffen Multi Rota Tray Variable Neutral Density Kit is a single geared rotating tray that allows the use and rotation of a 138mm Circular Polarizer filter and a 4x5.65" Circular Polarizer simultaneously. The tray is designed for use with matte boxes that lack a rotating filter stage, or for instances where a secondary rotating filter stage is required in a non-rotating stage. It can be used with just the included geared 138mm Circular Polarizer, or paired with the included 4x5.65" Circular Polarizer to function as a variable neutral density filter or to produce warm/cool effects, depending on the direction the tray and 4x5.65" filter are facing. A spare 4x5.65" Circular Polarizer is included..
