LIGHT REDUCTION & COLOR IMPROVED - Variable filter offers 1 to 5 stops light reduction, including ND2/ND4/ND8/ND16/ND32, the proper range from a cloudy day to a sunny day. CPL is widely used to enhance color and contrast in white cloud and blue sky photography. New Brass Frame Design: Classic brass frame with CNC design, strong and durable, easy to install on lenses. A leather case protects the filter. 36 layers of coating: both lenses have nanometer coatings, are waterproof and scratch resistant, ensuring color balance, without chromatic alteration and without affecting image quality. Ultra-thin frame & Vignetting-Free: machined with 0.01mm precision, the ultra-thin frame perfectly avoids vignetting on telephoto and wide-angle lenses. Advanced Coating Technology: K&F CONCEPT with its well-known coating technology has reduced reflectivity to 0.15% and guaranteed high transmittance, effectively reducing ghost images and reflections and restoring true color.
