NiSi Filter AIR Protector 105mm

NiSi Filter AIR Protector 105mm – 99.8% Light Transmittance for Preserving Lens Performance

The NiSi AIR Protector 105mm provides dependable physical protection for your lens while preserving optical performance. It maintains near-perfect transparency with 99.8% light transmittance and is engineered to support high-resolution sensors without introducing unwanted reflections or color shifts.

Key Benefits

• Protects your lens from dust, moisture and everyday wear while remaining optically neutral.
• Maintains image quality with 99.8% light transmittance and design optimised for high-resolution (8K) sensors.
• Easy to keep clean thanks to waterproof and oil-resistant coatings that repel moisture, fingerprints and smudges.
• Wide compatibility across popular lens sizes from compact primes to professional telephotos, available in 40.5–105mm sizes.

Features and Optical Design

The AIR Protector uses premium optical components and coatings to avoid compromising your lens’s native performance. Specifically, NiSi uses ultra water-white optical glass to preserve neutral color balance and outstanding light transmission. In addition, a double-sided multi-layer nano coating reduces internal reflections and improves contrast, keeping images clean and crisp in challenging lighting.

Furthermore, the filter features a 24+24 layer coating structure—48 layers in total—combining protective and anti-reflective treatments for long-lasting clarity and stable performance over time.

Construction and Handling

The filter mounts in an ultra-thin aluminum frame. This lightweight and durable construction helps prevent vignetting on wide-angle lenses while the knurled edge simplifies installation and removal. In short, the design balances physical protection with practical handling for everyday use.

Cleaning and Maintenance

NiSi applies a waterproof and oil-resistant coating to the filter surface. As a result, the filter repels moisture, fingerprints and smudges, which makes cleaning effortless and helps preserve flawless optical clarity during shoots.

Sizes and Compatibility

The AIR Protector is available in sizes covering common lens threads, from 40.5mm up to 105mm. This range offers compatibility for many compact primes through professional telephoto lenses.
