The Viltrox Pro Series Ultra Slim MC UV Protection Filter in 82 mm size offers professional lens protection with exceptional optical performance. This ultra-thin filter features multi-coating technology that provides 99.5 percent light transmission while effectively blocking UV rays below 390 nm wavelength, preventing bluish color casts in photographs. Made from B270 professional optical glass, the filter maintains high surface flatness and parallelism through precision grinding processes, ensuring minimal impact on image quality. The 18-layer high transmission coating offers even light distribution with only 0.3 percent surface reflection, reducing lens reflections and light scattering while maintaining balanced color reproduction in the visible spectrum of 420-700 nm. The 3.2 mm ultra-thin aluminum alloy frame prevents vignetting with wide-angle lenses and features a matte coating to absorb stray light. With a 96HD hardness rating, the filter provides excellent scratch resistance and durability for demanding shooting situations. Additional protective features include water-repellent and oil-resistant coatings that repel moisture and dirt while maintaining smooth surface properties. The precision-crafted CNC aluminum frame offers lightweight strength with good corrosion resistance and thermal stability. This filter serves as a reliable primary protection for camera lenses while preserving optical clarity and color accuracy, making it suitable for professional photography applications where maintaining image quality alongside lens protection requirements is essential.
