The 82mm X4 Uv Traction Filter, with its brass frame, Schott glass, and Nanotec coating, is a testament to superior optical technology. This high-quality filter is renowned for its unparalleled optical resolution, surpassing all other protection filters in the market. Engineered by Breakthrough Photography, the X4 Uv filter incorporates state-of-the-art MRC16 and nanotec nano coating layers. These uniformly applied layers enhance light transmission up to 99.4%, creating a protective shield that's structurally harder than the glass itself. This innovative design ensures the filter can withstand the rigors of professional outdoor photography.The X4 Uv filter features Schott Ultrawhite B270 optical glass, made in Germany, known for its critically sharp imaging capabilities. This durable glass offers high optical clarity and resistance to scratches and abrasions, making it an effective tool for photographers.The nanotec Nano Coating layer, built into both sides of the filter, repels dirt, water, and other elements by beading rather than absorbing. This makes cleaning the filter faster and easier than ever before, ensuring you can focus on capturing the perfect shot.The X4 Uv filter's design is a breakthrough in filter technology. It features a full traction texture around its entire circumference, making it easier to securely attach and remove. This filter is machined from brass, stronger than aluminum, providing a more reliably solid feel and less binding and jamming on lenses and with other filters.The X4 Uv filter also features an ultra-slim double-threaded 3.2mm Traction Frame. This eliminates vignetting and light falloff on full-frame wide-angle setups, while still being compatible with all your lens caps. The double-threaded traction frame will accept all of your filters and existing lens caps, making it a versatile addition to your photography equipment.Every X4 Uv filter comes with a unique serial number laser engraved onto the interior frame. This allows Breakthrough Photography to provide personalized support and confirm the authenticity of the product. With every purchase, Breakthrough Photography also contributes 5% directly to non-profits, demonstrating their commitment to making the world a better place. In summary, the 82mm X4 Uv Traction Filter is a professional, innovative, and high-quality tool designed to enhance your photography experience and protect your camera lens from the harmful effects of Uv light..
