NiSi Filter Protector Pro Nano Huc 67mm – Ultra-thin 3.5mm frame to minimize vignetting

The NiSi Filter Protector Pro Nano Huc 67mm shields your lens front element from dust and impact while maintaining excellent image transmission. It uses high-quality optical glass with nano coatings on both sides to ensure clear light passage. The filter’s ultra-thin aluminum frame and careful finishing make it suitable for wide-angle use without introducing unwanted vignetting.

Key features and materials

NiSi designed this protector to combine protection and optical performance. Below you find the core features as provided:

• Ultra thin frame (3,5mm) — the slender aluminum frame helps minimize vignetting on wide-angle lenses.
• High quality optical glass — the glass achieves high transmittance (>99,3%) and a highly smooth surface with only 0,3% reflection.
• Nano coating on both sides — the exclusive creative “U” type Nano coating is applied to both surfaces of the glass.
• Hardened waterproof coating — the filter receives a coating designed to resist water and make care easier.
• Protects the lens — it guards the front element from dust and damage due to impact or handling.
• Easy to clean — the coatings and smooth surface facilitate routine cleaning.
• Durable frame finish — superfine dull polishing and elaborate knurling reduce the risk that the frame will blanch from repeated rotation.

How it helps on-camera

Use this protector whenever you need simple, reliable protection without altering image quality. Because the frame is only 3,5mm thick, you can mount it on wide-angle lenses with reduced risk of darkened corners. Meanwhile, the high transmittance and low reflection maintain the lens’ native light transmission.

Care and handling

Clean the protector gently to preserve its Nano coatings and maintain high transmittance. The hardened waterproof coating and smooth glass surface make cleaning straightforward. Also, the knurled frame provides a secure grip for installation and removal while reducing cosmetic wear from repeated rotation.

FAQ
