The PolarPro Cinema Series Shutter Filter Collection 3-Pack for DJI Osmo Action is made from PolarPro Cinema Series glass with a machined aluminum frame. Each included filter features the magnetic HotSwap system that allows you to easily remove or swap out the filter for another, without unthreading the base from your Osmo Action. The combination ND4/PL filter requires a 2-stop exposure compensation, the ND8/PL requires a 3-stop compensation, and the ND16/PL requires 4 stops of compensation. This allows you a choice in adjusting your iris settings. Each filter is splashproof and has 16 layers of coatings that provide protection from reflections, scratches, as well as water and oil droplets.
The circular polarizer rotates to reduce glare and enhance color and contrast/saturation and will not interfere with autofocus or cause unpredictable darkening of your image as can happen with linear polarizers
The circular polarizer itself requires a 1.6-stop compensation, and the combination ND4 adds only 0.4 stops for a total of 2 stops of exposure compensation; likewise, the ND8/PL requires only 3 stops and the ND16/PL combination requires 4 stops of exposure compensation
Magnetic HotSwap system replaces stock UV filter and allows you to quickly remove or change the filter without unthreading the base
Cinema Series glass features low refractive index, color neutrality, and perfect target transmission
Each filter features optical, hydrophobic, and scratch-resistant coatings for optical performance, resistance to oil and water, as well as scratch protection
Redesigned magnetic filter case with easier filter access and visibility
