Designed for mobile filmmakers using the iPhone 11, the LiteChaser Pro Variable Neutral Density 3-5 Filter from PolarPro cuts the amount of light entering your phone's lens by 3 to 5 stops, which allows shutter speeds to be lowered to more cinematic levels. Thanks to laser-etched stop indicators, you'll be aware of how many stops the available light is being reduced by. Built using an aluminum frame, this filter also features a 16 layer multi-coating to help reduce flaring, fingerprints, and oil, as well as an optical density of 0.9 to 1.5 and a light transmission of 12.5 to 3.125%.
