Key features and benefits

This protector filter focuses on protection and optical performance. Below you find the main features exactly as specified:

• 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.
• Protect the lens from dust, damage to the front element
• Easy to clean

Design and construction

The frame is made from high quality aluminum and measures only 3,5mm in thickness. Because of this slim profile, the filter fits well even on super wide angle lenses and helps avoid vignetting. Additionally, the frame receives superfine dull polishing and elaborate knurling. These finishing steps reduce the risk of the frame blanching from repeated rotation and maintain a consistent feel during use.

Optical surface and coatings

NiSi uses high quality optical glass designed for high light transmission. The nano coating applies on both sides of the glass and the manufacturer states a transmittance of >99,3% with only 0,3% reflection. The filter also includes a hardened waterproof coating to help protect the surface from moisture while preserving the optical characteristics.

Care and handling

The filter is described as easy to clean and features coatings intended to maintain surface quality. The refined frame finish and knurling support repeated use without visible wear, and the waterproof treatment contributes to surface durability.
