Ultra-thin MC UV Protection FiltersHigh light transmission / Waterproof & Stain-resistantVarious Sizes AvailableThe Viltrox Pro series is a professional imaging-grade , ultra-thin, high-light-transmission lens UV protection filter. It is built with multi-layer coating, providing light transmission as high as 99.5%99.5% Light TransmissionThe filter lens adopts 18-layer high-transmission coating technology, which allows more uniform light transmission and more balanced color performance. 0.3% surface reflectivity, effectively reducing reflection on the lens surface and reducing light scattering and interference.High Light Transmission, Low ReflectivityIn the visible band (420-700nm), the average light transmittance of the Viltrox series UV mirror is as high as about 99%, which can achieve clearer, brighter, and more realistic image effects, making photographic works full of delicate and vivid colors.High Precision, Precision MachiningUsing multiple grinding precision processing techniques to ensure that after each piece of glass undergoes rigorous optical processing, the surface flatness and parallelism of the filter reach a high level of precision.Optical Glass Focus on QualityMade of B270 professional optical glass material. It is thin and tough, has excellent hardness, is durable and scratch-resistant, and always provides first-line protection for your camera lens.Multi-layer Coating, UV ResistantThe lens adopts surface UV cut-off coating, which effectively blocks UV rays below 390nm, thus effectively avoiding the bluish phenomenon of photos caused by excessive UV rays.Waterproofing/Oil and Smudge ResistanceThe surface of the lens is coated with a waterproof and anti-oil stain coating to keep it smooth and smooth. It has super hydrophobic properties and can effectively resist the adhesion of oil stains.Aluminum Alloy Frame, Strong and DurableThe frame is made of precision aluminum alloy and processed by precision CNC. It is light in weight, high in strength, good in corrosion resistance, high in heat resistance and good in low temperature performance. The frame is treated with matte coating, which can effectively absorb stray light and reduce reflections.Excellent Details and Superior Experience 3.2mm ultra-thin aluminum alloy frame, easy to use as a wide-angle lens, no dark corners when shooting 96HD high hardness, scratch-resistant and wear-resistant, ready to meet the challenges of various shooting environments, making shooting more secureIf you don't know the lens diameter, look for the symbolFor common lens brands, the diameter is printed on the front or side of the lens. Find the number after the character to determine the lens diameter.
