I used this for about two months, but I'm selling it because I've sold the lens. I think the condition is good. This is a completely colorless and transparent lens protection filter designed to prevent dust and debris from scratching the lens. This filter features "Super EBC Coating," which applies multiple layers of thin film coating. This effectively suppresses light reflection with a surface reflection rate of 0.3% or less, allowing the lens to reproduce colors as they are and supporting ultra-high-definition photography. ■ Model Number: PRF-77 ■ List Price: 9,900 yen (tax included) ■ Filter Diameter: Ø77mm ・Compatible Models: Fujinon Lens GF55mmF1.7 R WR / GF80mmF1.7 R WR / GF110mmF2 R LM WR / GF32-64mmF4 R LM WR / XF50mmF1.0 R WR / XF16-55mmF2.8 R LM WR / XF100-400mmF4.5-5.6 R LM OIS WR
