Experience unparalleled color fidelity and peerless image quality with the 72mm 6-Stop X4 Neutral Density (ND) Filter, a premium choice for the discerning landscape photographer seeking to master light and exposure. Our relentless pursuit of perfection has culminated in the X4 ND's exceptional color neutrality, setting a new benchmark in the industry for color accuracy and optical precision.Crafted with Schott Superwhite B270 optical glass, renowned for its ultra-clear properties and superior light transmission across the ultraviolet, visible, and infrared spectrums, this ND filter ensures your images retain the highest fidelity. The continuous draw glass manufacturing process yields a pristine surface that is perfectly receptive to our advanced Mrc and nanotec coatings.Our state-of-the-art multi-resistant coating (MRC16) is applied to both sides of the glass, enhancing durability and reducing reflections to a minimum. This innovative 16-layer coating process ensures that less light is lost, boosting contrast and color vibrancy in your photographs. The result is a noticeable improvement in image clarity, free from the common issues of low light transmission and unwanted flaring.Designed to endure the rigors of fieldwork, the X4 ND filter boasts a weather-sealed construction that stands up to extreme conditions, including wind, saltwater, dust, and other abrasive elements. The nanotec Nano Coatings Technology further fortifies the filter by repelling water and resisting smearing, ensuring your filter remains clean and functional in any environment.The X4 ND's breakthrough design extends to its robust filter frame, meticulously engineered from high-quality brass and featuring our signature traction frame. This thoughtful design allows for effortless attachment and secure operation, even when wearing gloves in challenging weather conditions.Unlike many neutral density filters that suffer from a pronounced blue or magenta color cast, especially at higher ND factors, the X4 ND filter achieves the most color-neutral performance through an innovative manufacturing process that deviates from conventional methods. Our rigorous testing with transmission curve spectrometers confirms the X4 ND's superior color neutrality, with a transmission curve that remains flat and consistent through the visible spectrum and into infrared wavelengths.Embrace the world's most color-neutral ND filter, guaranteed to deliver the professional results you demand. The 72mm 6-Stop X4 Neutral Density Filter by Breakthrough Photography is the reliable, high-quality, and durable choice for photographers who refuse to compromise on image quality..
