Description
The lens material is top Japanese optical glass, with 18 layers of anti-reflection coating, which can reduce the reflected light on the filter surface
Compared with ordinary CPL, the surface coating of this lens ensures that the filter will not be moldy and foggy during long-term use. It can eliminate 99.9% of polarized light and has a high transmittance of 45%.
The frame is made of aviation-grade aluminum, and the ultra-thin design ensures that there will be no vignetting at the wide-angle end
The surface of the mirror frame is treated with oxidation and sandblasting, which can effectively avoid the entry of stray light to the greatest extent. It adopts CNC trapezoidal pattern design, which increases friction during rotation and is easy to install
A vacuum-packed cleaning cloth is provided as a gift, which is safe and clean, ensuring that the lens/filter will not be damaged
