Breakthrough Photography 67mm 6-Stop X4 Neutral Density Filter
After years of meticulous research and innovative manufacturing techniques, we present the 67mm 6-Stop X4 Neutral Density Filter, a game-changer for landscape photographers seeking the most color-neutral ND filter available. This breakthrough product is the result of our relentless pursuit of unparalleled color neutrality and a complete redesign of the filter frame.The X4 ND filter, touted as the world's sharpest ND filter, is crafted from SCHOTT Superwhite B270 optical glass, an ultra-clear crown glass. This high-quality glass is created by melting high-purity raw materials and using the continuous draw process, resulting in exceptional transmission in the ultraviolet, visible, and infrared spectrums. Its high surface quality readily accepts our state-of-the-art MRC and nanotec coatings.Our proprietary MRC16, a multi-resistant coating, is applied to both surfaces of the glass disk. This optical coating reduces reflection, increases surface durability, and is structurally harder than the glass itself. The reduced reflections enhance the efficiency as less light is lost, and the elimination of stray light improves the image contrast, resulting in better contrast and color in your photographs.The X4 ND filter is designed to be a workhorse for field work, engineered to withstand extreme wind, salt water, dust, and other abrasive conditions and elements. Our state-of-the-art nanotec Nano Coatings Technology ensures that water and other elements bead rather than absorb and smear, keeping your filter clean and clear.Unlike many neutral density filters on the market that exhibit a strong blue or magenta cast, the X4 ND filter offers the most color-neutral performance. This is achieved through an alternative manufacturing method to the conventional oven process. The X4 ND filter maintains a well-controlled and flat transmission throughout the visible spectrum and into IR, making it the most color-neutral ND filter with the flattest transmission curve.The filter frame of the X4 ND filter is constructed of high-quality brass and CNC machined with our signature traction frame, making it easy to attach and remove securely, even in cold conditions with gloves on. We stand behind the X4 ND filter with our 25 Year Ironclad Guarantee, promising optimal clarity and color neutrality even in the harshest of conditions. Experience the difference with the 67mm 6-Stop X4 Neutral Density Filter, the most reliable and effective tool for your photography needs.
