The moment you use the X4 CPL, you know youve never used anything like it. Featuring our all-new American made CPL film and an all-new brass traction frame features best-in-class design and durability. Our all-new and internally developed CPL film is at the core of the X4 CPL, and we manufacture it right here in California. To achieve the worlds most color neutral performance, we had to develop a unique approach to manufacturing rather than selecting off-the-shelf CPL film common among filter manufacturers, which is designed and intended for LCD panels, not photographic optics. Low light transmission and green flaring are common problems with uncoated glass. As MRC coatings are added to each side of the optical disk light transmission steadily increases with flaring steadily decreasing. In our lab tests light transmission apexes at about 16-layers of MRC, and slowly decreasing in transmission at 18 and above. 8-layers of MRC are applied evenly to both sides of each optical disk resulting in MRC16. Benefits: Our X4 CPL to perform with optimal optical clarity and color neutrality for 25 years even in the harshest of conditions.Our X4 CPL is designed specifically as a workhorse CPL for field work, built to withstand extreme wind, salt water and dust.25 years support Features: SCHOTT Superwhite B270 optical glass made in Germany Nano coating layer technology, called nanotec Transmission Curve design Item includes: 1 x 55mm X4 CPL Filter Plastic Storage Case Lens Cloth 25 Year Guarantee We stand behind all our products 100%.
