NiSi Filter Protector Pro Nano Huc 62mm

NiSi Filter Protector Pro Nano HUC 62mm – Ultra-thin 3.5mm frame to minimize vignetting

The NiSi Filter Protector Pro Nano HUC 62mm protects the front element of your lens while maintaining high image quality. It uses high quality optical glass with a Nano coating applied to both sides. The filter frame is made from aluminum and is designed to be ultra thin, helping to avoid vignetting on wide-angle lenses.

Key features

• Ultra thin frame (3,5mm) to minimize vignetting on wide angle lens
• High quality optical glass for high transmittance (>99,3%) and highly smooth surface with only 0,3% reflection
• Exclusive creative "U" type Nano coating
• Hardened waterproof coating
• Protects the lens from dust and damage to the front element
• Easy to clean

What this filter does for your lens

This protector acts as a first line of defense against dust and impact to the front element. Because it transmits more than 99.3% of light and keeps surface reflections to about 0.3%, it preserves the optical performance of your lens. The waterproof, hardened coating helps repel moisture and makes routine cleaning straightforward.

Design and handling

The frame is machined from aluminum and measures only 3,5mm in thickness. This ultra-thin construction helps the filter sit close to the lens front element, reducing the risk of vignetting when you use wide-angle lenses. Additionally, NiSi applies superfine dull polishing and elaborate knurling to the frame. These finishing steps prevent the frame from blanching or showing wear from repeated rotation, so you can attach and remove the filter without cosmetic damage to the finish.

Coating details

NiSi uses an exclusive "U" type Nano coating on both sides of the optical glass. This Nano coating improves surface smoothness and contributes to the low reflection figure (0,3%). The hardened waterproof layer adds protection and makes the filter easier to clean after exposure to dust, water droplets or fingerprints.

FAQ

Question: Will this protector cause vignetting on wide-angle lenses?

Answer: The ultra thin 3,5mm aluminum frame is specifically designed to minimize vignetting on wide-angle lenses. Its slim profile reduces the chance that the filter will intrude into the field of view.

Question: How does the Nano coating affect image quality?

Answer: The exclusive "U" type Nano coating on both sides improves surface smoothness and optical transmission. The filter maintains high transmittance (>99,3%) while keeping surface reflections low (0,3%), which helps preserve the lens's original image quality.

Question: Is the filter easy to clean and maintain?

Answer: Yes. The hardened waterproof coating helps repel moisture and contaminants, making the filter easier to clean after exposure to dust, water or fingerprints. Regular gentle cleaning will keep the surface clear.

Question: Will the filter frame show wear after repeated use?

Answer: NiSi uses superfine dull polishing and elaborate knurling on the frame to prevent blanching from repeated rotation. This finishing improves durability and keeps the frame looking consistent after frequent attachment and removal.
