The Viltrox Pro Series Ultra Slim MC UV Protection Filter with a diameter of 95 mm is a professional accessory for lens protection in imaging quality. This ultra-thin filter features multi-coating technology that achieves 99.5 percent light transmission with minimal surface reflection of 0.3 percent, ensuring optimal image quality without compromising optical performance. Made from B270 professional optical glass, the filter offers excellent hardness and scratch resistance with a slim 3.2 mm aluminum alloy frame that prevents vignetting with wide-angle lenses. The 18-layer high transmission coating provides uniform light transmission across the entire visible spectrum from 420 to 700 nm with balanced color reproduction and reduced light scattering. The UV blocking coating effectively blocks ultraviolet rays below 390 nm, preventing the bluish tint often caused by excessive UV exposure in photography. The surface treatment includes water-repellent and oil-repellent properties with superhydrophobic features that resist dirt and stains. The precisely CNC-machined aluminum alloy frame has a matte finish that absorbs stray light and reduces reflections while offering high strength, corrosion resistance, and excellent thermal performance. With a 96HD hardness rating, this filter provides lasting protection against scratches and environmental influences while maintaining optical clarity. The ultra-slim design ensures compatibility with wide-angle lenses without dark corners or vignetting in your photos. This professional filter preserves the original optical properties of your lens while providing essential protection against dust, moisture, and physical damage.
