ProMaster 62mm HGX Prime Circular Polarizer (ProMaster SKU: 6837 | Helix SKU: PR6837). This circular polarizer is designed to reduce reflections and deepen color saturation while allowing about 30% more light through than typical polarizers for brighter exposures and improved image quality. Built for high-end optics, each HGX Prime filter is individually ground and polished with black-rimmed glass and advanced multi-coatings to deliver exceptionally clear light to your sensor. A Repellemax II Anti-static barrier helps repel dust, dirt, oil, water and fingerprints for easy maintenance. The filter uses ultra-hardened glass with a scratch-resistant coating for long-lasting durability. Optical highlights include extremely high visible light transmission for brighter results, state-of-the-art multi-coatings to minimize flare and internal reflections, and precision construction for reliable performance.
