An exceptional tool for professional photographers, the Breakthrough Photography X2 ND Traction Filter is meticulously crafted with superior AGC glass from Japan. This 82mm filter is designed to enhance your photography experience by reducing the amount of light entering your camera lens, enabling wider apertures and faster shutter speeds in low light conditions. The X2 ND filter offers a choice of 3-stop or 6-stop light reduction, catering to a variety of shooting scenarios. Its weather-sealed traction frame ensures easy attachment and removal, even in challenging weather conditions, making it a reliable companion for outdoor photography. This high-quality filter is not just about functionality, but also about durability. It features a multi-resistant coating (MRC-8) applied in four layers on each side of the optical disk, totaling eight MRC layers. This coating is structurally harder than the glass itself, enhancing the scratch resistance of the optical surfaces and extending the filter's lifespan. Precision is key in the design of the X2 ND filter. Each filter is CNC machined with narrow tolerances and undergoes a strict quality control process, ensuring a product with minimal defects. The result is a filter built to last at least 25 years, making it a long-term investment for your photography gear. The X2 ND filter also addresses the issue of vignetting with its 3.5mm ultra-slim double-threaded Traction frame profile, designed to eliminate vignetting on wide-angle full-frame setups. This thoughtful design allows the filter to accept all lens caps while staying below the 3.7mm threshold where vignetting becomes noticeable. The X2 Traction frame features laser engraved lettering, ensuring the markings won't fade or peel off with consistent use. Each filter also comes with a unique serial number, allowing Breakthrough to track your product and record any issues for future product design improvements. For photographers seeking to maintain their lens' optimal performance, the X2 ND filter offers weather-sealed durability. As recommended by Canon, Nikon, and Sony, using a protective filter completes a lens' weather-seal, protecting it from dust and water damage. In summary, the Breakthrough Photography X2 ND Traction Filter is a high-quality, durable, and effective tool for professional photographers seeking to enhance their low light photography while protecting their valuable lenses.
