Feature(may vary by option.)
●CPL filter function: with circular polarising filters, you can use unwanted reflections from non-metallic surfaces such as water, glass, etc. Can also improve colour contrast and saturation, especially in blue sky and white clouds. New and old packaging will be sent at random
●24 multi-layer coatings: Double-sided polishing technology on glass, waterproof, oil-resistant nanometer coatings that protect the filter and reduce reflections coming from the filter itself, durable enough.
●Ultra slim aviation aluminium frame: only 5.3 mm thick, avoids vignetting on wide angle lenses, with CNC anti-slip design for easy removal and installation of the filter.
●Import AGC glass: The CPL filter made of imported Japanese optical AGC glass ensures HD image quality.
●Note: This filter only fits 77mm camera lenses. Please check your lens size before you order it. The number next to the "Ø" (diameter) symbol represents your lens size, please choose the same size filter.
