NiSi Filter Protector Pro Nano HUC 46mm – Ultra-thin 3.5mm Frame to Reduce Vignetting

The NiSi Filter Protector Pro Nano HUC 46mm protects the front element of your lens from dust and impact. It uses high quality optical glass with Nano coating on both sides, and it lets 99.3% of light pass through while keeping surface reflections at 0.3%.

Built for protection and optical clarity

This protector sits in a lightweight aluminum frame that measures only 3.5mm in thickness. Because the frame is ultra thin, the filter fits well on wide-angle and even super wide-angle lenses, helping to avoid vignetting.

Additionally, the glass features an exclusive "U" type Nano coating on both sides and a hardened waterproof coating to resist water and make cleaning easier. Superfine dull polishing and elaborate knurling on the frame prevent blanching from repeated rotation.
