Let the 62mm X4 Circular Polarizer Filter with MRC16 & nanotec Coating Layers revolutionize your photography experience. This advanced circular polarizer, crafted by Breakthrough Photography, is unlike anything you've used before. It's designed with an all-new American-made CPL film and a robust brass traction frame, ensuring unrivaled design and durability.This filter stands out as the world's most color-neutral CPL, thanks to Breakthrough Photography's innovative CPL film, manufactured right here in California. Unlike the off-the-shelf CPL films used by other manufacturers, the X4 CPL film is specifically designed for photographic optics, ensuring warm and lively images without the common yellow cast.The X4 CPL filter's transmission curve is meticulously measured using spectrometers, ensuring the most color-neutral performance of any CPL filter. This filter effectively reduces the transmission increase at 650nm and controls transmission into the IR range, resulting in a decline in IR transmission across the visible spectrum.The X4 CPL filter is a game-changer for outdoor photographers, helping to expand your camera's dynamic range. It effectively removes glare, adding vibrancy and contrast to your images, and revealing details that would otherwise remain unseen. The filter's circular design allows you to control the amount of polarization, enhancing the dynamic range, especially at higher elevations.The X4 CPL filter is not just about performance; it's also about durability. Designed as a workhorse for field work, it can withstand extreme wind, salt water, dust, and other abrasive conditions. It incorporates Breakthrough Photography's state-of-the-art nanotec Nano Coatings Technology, which repels water and other elements, ensuring the filter's longevity.The X4 CPL filter features SCHOTT Superwhite B270 optical glass, known for its ultra-clear quality and excellent transmission in the ultraviolet, visible, and infrared spectrums. This high-quality glass is coated with Breakthrough Photography's proprietary MRC coating, reducing reflection, increasing surface durability, and improving contrast and color in your images.Experience the world's sharpest CPL filter with the 62mm X4 Circular Polarizer Filter with MRC16 & nanotec Coating Layers. This filter guarantees optimal optical clarity and color neutrality for 25 years, even in the harshest of conditions.
