This is a high-performance 40.5mm lens protection filter with a 0.3% reflection rate. I purchased it new on Amazon on July 9, 2025, for use with the Sony α7c II lens kit, but I am selling it unopened because I no longer have a use for it due to a model change. - Brand: MARUMI - Model Name: LENS PROTECT S-5 - Size: 40.5mm - Reflection Rate: 0.3% - Country of Manufacture: Japan Thank you for looking.
