The mounted Revar Cine Circular Polarizer Pola+ for Matte Boxes from Revar Cine is a 138mm premium polarizer made from Schott B270 glass and features a broad-band anti-reflective coating to reduce flare. A circular polarizer filter removes unwanted reflections from nonmetallic surfaces such as water or glass, and it can also saturate colors, providing better contrast. It can clear up haze in distant landscapes and provides a more saturated, vivid blue sky.

Q: 1. Hi just wondering if when using this filter on a 4.5mm wide angle B4 ENG lens, weather you get any vignetting when fully wide as wanting to put in in the front tray of my Croszniel matte box not the rotating back one. Based on filter being 4 x 5.65 sizing as mentioned above?

A: The included circular polarizer filter is manufactured from Schott B270 glass and is considered a mid-efficiency filter. It would be only be a small upgrade in price to purchase the empty Rota-Tray and put the Schneider True-Polarizing Water White Glass Filter in to the system.
