The 82mm JetMag Pro 82MAG Natural Night Magnetic Filter from NiSi is designed for use with their JetMag Pro magnetic filter system, allowing you to quickly swap filters without having to unscrew each one once you've attached the JetMag Pro adapter ring. This filter helps block out artificial light sources like street lights and reduces orange and yellow color casts for clear, sharp nighttime photography. Its antireflective and waterproof nano coatings also help protect the surface of the filter, maintaining durability and image quality over time. The purple handles also make it easy to distinguish from your other filters.
