Explore the unparalleled performance of the 62mm 3-Stop X4 Neutral Density Filter, a groundbreaking product designed for the discerning landscape photographer. This filter, a result of cutting-edge research and innovative manufacturing techniques, offers the most color-neutral Nd filter experience on the market. The X4 Nd filter is crafted with Schott Superwhite B270 optical glass, an ultra-clear crown glass produced by melting high purity raw materials and using the continuous draw process. This results in superior transmission across the ultraviolet, visible, and infrared spectrums, and a high-quality surface that perfectly accommodates our state-of-the-art Mrc and nanotec coatings.Our proprietary MRC16 coating, an optical layer applied to both surfaces of the glass disk, reduces reflection and enhances surface durability. This coating is structurally harder than the glass itself, and the reduced reflections improve efficiency as less light is lost. The result Improved contrast and color in your images.The X4 Nd filter is designed to be a workhorse for field work, built to withstand extreme wind, salt water, dust, and other abrasive conditions. Our state-of-the-art nanotec Nano Coatings Technology ensures that water and other elements bead rather than absorb and smear, providing additional protection for your filter.Unlike many neutral density filters 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, ensuring optimal color neutrality.The filter frame has been redesigned from the ground up, constructed of high-quality brass Cnc machined with our signature traction frame. This makes the X4 Nd filter easier than ever to attach and remove securely, even in cold conditions or when wearing gloves.The 62mm 3-Stop X4 Neutral Density Filter is not just a product, but a promise of optimal clarity and color neutrality for 25 years, even in the harshest of conditions. Experience the difference with our world's sharpest and most color-neutral Nd filter..
