The Urth 55mm Magnetic Ethereal Black Mist Plus+ is a precise optical filter for professional photographers and enthusiasts. This 55mm diameter filter features a magnetic mounting system for quick lens changes without threads, compatible with Urth magnetic filter holder systems. The Black Mist Plus+ effect creates subtle diffusion that softens highlights while preserving shadow details and contrast, allowing for a cinematic look with controlled halation. Made from high-quality optical glass, the filter offers multi-layered nanocoating technology that reduces reflections, minimizes lens flares, and ensures 99.9% light transmission for accurate color reproduction. The slim aluminum frame is 4.5mm thick to avoid vignetting with wide-angle lenses, featuring a durable brass mounting ring for a secure fit. The hydrophobic coating repels water, oil, and fingerprints, making cleaning and maintenance easier. This filter is suitable for portrait, landscape, and creative photography applications where controlled diffusion is desired. The magnetic system allows for stacking multiple filters without significant increase in thickness. The product comes with a protective storage case and a microfiber cleaning cloth. Dimensions are 55mm filter diameter with a 0.75mm pitch standard thread, weighing approximately 45g. It is the successor model to previous magnetic filter designs with improved coating durability and increased magnetic holding strength.
