NiSi Filter Protector Pro Nano Huc 86mm

NiSi Filter Protector Pro Nano HUC 86mm – Ultra-thin 3.5mm Frame to Minimize Vignetting

This NiSi Filter Protector Pro Nano HUC 86mm protects the front element of your lens from dust and impact. It uses high quality optical glass with a U-type nano coating on both sides and allows high light transmission. The aluminum frame measures only 3.5mm in thickness, making the filter ultra thin so it fits even on super wide-angle lenses and helps avoid vignetting.

Key features

• Ultra thin frame (3,5mm) – The slim 3.5mm aluminum frame minimizes vignetting on wide-angle lenses and helps the filter sit close to the lens for a clean optical path.
• High quality optical glass – The glass provides very high transmittance (>99.3%) and a highly smooth surface, with only 0.3% reflection to preserve image quality.
• Exclusive creative "U" type Nano coating – The U-type nano coating is applied for enhanced surface properties on both sides of the glass.
• Hardened waterproof coating – The surface includes a hardened waterproof layer to repel moisture and help maintain clarity in damp conditions.
• Protects the lens – The filter shields the front element from dust and potential damage from impact or contact.
• Easy to clean – The coated glass and smooth surface allow for straightforward cleaning and maintenance.

Build and handling

The frame is made from high quality aluminum and receives superfine dull polishing. In addition, elaborate knurling on the filter ring improves grip and ensures the frame will not blanch from repeated rotation. These finishing details aid reliable mounting and removal while maintaining the frame’s appearance over time.

Use cases

Use this protector whenever you need to guard your front element without affecting image transmission. Because the filter is ultra thin and transmits over 99.3% of light with minimal reflection, you can leave it mounted during shooting on wide-angle or general-purpose lenses to protect the glass while preserving image quality.

Care and maintenance

Clean the filter with appropriate lens cleaning tools. Thanks to the nano and waterproof coatings, dirt and moisture remove more easily than on untreated glass. Regular, gentle cleaning preserves both optical performance and the finish on the frame.

FAQ

• Question: Will this filter cause vignetting on wide-angle lenses?
  Answer: The filter features an ultra-thin 3.5mm aluminum frame designed to minimize vignetting and to fit even on super wide-angle lenses, reducing the chance of darkened corners.
• Question: How much light does the NiSi Pro Nano HUC transmit?
  Answer: The high quality optical glass offers greater than 99.3% light transmittance and a highly smooth surface with only 0.3% reflection, preserving the lens’s light throughput and image clarity.
• Question: Does the filter protect against moisture and make cleaning easier?
  Answer: Yes. The filter includes a hardened waterproof coating and a U-type nano coating on both sides, which help repel moisture and allow easier cleaning of the glass surface.
• Question: Will the frame wear with repeated use?
  Answer: The frame receives superfine dull polishing and elaborate knurling to improve grip and to prevent blanching from repeated rotation, helping the filter retain its finish during regular mounting and removal.
