NiSi Filter Protector Pro Nano Huc 105mm – Ultra-thin 3.5mm Frame to Minimize Vignetting

The NiSi Filter Protector Pro Nano Huc 105mm protects your lens front element from dust and impact while maintaining excellent light transmission. It uses high-quality optical glass with a U-type Nano coating on both sides. The filter mounts in an ultra-thin aluminum frame, which helps reduce vignetting on wide-angle lenses.

Key features

• Ultra-thin aluminum frame (3.5mm) designed to minimize vignetting on wide-angle lenses.
• High-quality optical glass that allows over 99.3% transmittance and provides a highly smooth surface with only 0.3% reflection.
• Exclusive creative "U" type Nano coating applied on both sides for surface protection and optical clarity.
• Hardened waterproof coating to resist water and simplify cleaning.
• Superfine dull polishing and elaborate knurling on the frame to prevent blanching from repeated rotation.
• Protects the lens from dust and damage to the front element, and is easy to clean.

Why choose this protector

First, the ultra-thin 3.5mm frame reduces the risk of vignetting, making it suitable for use even on super wide-angle lenses. Second, the optical glass and nano coatings preserve image quality by maintaining very high light transmission and low reflection. Finally, the robust aluminum frame with careful finishing ensures reliable handling and long-term durability without cosmetic wear from frequent filter changes.

Specifications

Use cases

• Protects the front element of lenses on location shoots where dust or light impact is a concern.
