NiSi designed their new Rotating Circular Polarizer for 4 x 5.65" Matte Box with the cinematographer in mind. The filter fits into a standard matte box tray and uses a 0.8 gear to turn a circular polarizer in the assembly. This design makes it easy to find the polarization you want with the turn of a finger. The Rotating Circular Polarizer can greatly improve efficiency on time-sensitive shoots, making it a powerful tool for videographers and cinematographers.
