The K&F Concept NANO-X Series B270 CPL filter is made of the highest quality Japanese optical glass with almost zero light distortion.

28-layer double coating technology reduces glare and ghosting while protecting the filter from scratches, water and dust. The circular polarization function effectively filters out disturbing reflections on non-metallic surfaces such as water and glass.

The ultra-thin and light aluminum frame minimizes the effect of light and avoids the appearance of dark corners in wide-angle shots.

Double coating
