Achieves ultra-low reflection of 0.2%. Lens protection filter with water and oil repellent functions Kenko PRO1D Lotus II Protector 72mm Lotus leaves have the characteristic of repelling water droplets like beads, keeping them clean at all times. We have further evolved the "PRO1D Lotus" series of lens protection filters, named after the lotus. By adopting the newly developed "Digital Multi-Coating III," we have achieved ultra-low reflection of 0.2% surface reflection. By constantly attaching it to your lens, it protects the lens from water splashes, fingerprints, and other smudges. While possessing water and oil repellent functions that strongly repel water droplets and dirt, the newly developed Digital Multi-Coating III achieves ultra-low reflection, maximizing lens performance. I purchased it but have not used it as I was using another filter. It has only been opened once. Thank you.
