RF-CPL Filter 67mm TOKYO GRAPHER Tokyo Grapher's RF-CPL is a high-performance polarizing filter that condenses the technology and know-how of producing camera lens filters for 70 years. With 16-layer (both sides) anti-reflection multi-coating, it increases light transmission compared to general CPL filters without reducing the performance of the CPL. By using a rotating filter frame that is extremely thin and easy to use, it is a top-level CPL (Circular Polarized Light Filter) filter. In addition, it is water-repellent and oil-repellent, as well as highly durable coating that is resistant to scratches and dirt, allowing for long-term use.
