Lotus leaves repel water like a ball and keep them clean at all times. The lens protection filter from the "PRO1D Lotus" series named after the lotus is further evolved. Adopts the newly developed "Digital Multi-Coated III" to achieve ultra-low reflection of 0.2% of surface reflections. When you wear this lens at all times, it will protect the lens from splashes, fingerprints, etc. The newly developed digital multi-coat III provides ultra-low reflection and maximizes lens performance.
