SmallRig 52mm Magnetic Circular Polarizer CPL Filter 4216 HD Optical Glass Ultra Slim Frame

The SmallRig 52mm Magnetic Circular Polarizer (CPL) Filter 4216 is designed to enhance your photography by eliminating reflections from non-metallic surfaces like water, glass, and buildings. It significantly improves image saturation and contrast, making skies bluer and water more transparent. This filter can also reduce light by 1-2 stops, functioning as a neutral density filter.

* **Magnetic Design:** Features a quick-release magnetic attachment system for secure and stable connection to SmallRig 52mm magnetic filter adapter rings (sold separately).
* **Ultra-Slim Frame:** The 3.5mm CNC-machined aluminum alloy frame prevents vignetting, even when using ultra-wide-angle lenses. An anti-slip design allows for easy rotation to adjust polarization.
