The NiSi Air UV Protection Filter combines lens protection with optical performance suited to landscape, travel, and outdoor photography. It shields your lens from dust, scratches, and moisture while preserving the imaging capabilities of high-quality lenses, including when working in demanding outdoor conditions.
NiSi's ULRC (Ultra Low Reflective Coating) keeps light transmission high and reflections low. The filter reaches 99.9% peak transmission, averages 99.6% transmission between 420-680nm, and has just 0.1% reflectivity. These characteristics help maintain clarity with premium lenses while reducing glare and unwanted reflections.
Designed to support cameras with resolutions exceeding 100 megapixels, the Air UV preserves fine detail and image sharpness. Its high-resolution optical performance accommodates landscape, portrait, and commercial photography without compromising the resolving capabilities of the camera and lens.
- 48-layer ULRC nano-coating resists scratches, stains, water, and oil, helping the filter withstand the demands of professional photography and harsh outdoor environments.
- UV filtration blocks wavelengths below 395nm to reduce blue haze and ultraviolet interference. This helps preserve accurate colors and clear, sharp images in challenging lighting.
The filter uses carefully selected, lens-grade optical glass to maintain image quality. Each piece of glass is subject to strict quality control, supporting consistent optical performance rather than adding protection at the expense of clarity.
- An ultra-thin brass frame is designed to prevent vignetting, even with ultra-wide-angle lenses. Brass offers greater durability and resistance to deformation than aluminum, while the knurled edge makes the filter easier to install and remove.
Every Air UV filter is tested with a Shimadzu spectrophotometer to check transmission and reflectivity. This individual inspection verifies optical performance against NiSi's quality standards and supports consistency from filter to filter.
- A plastic storage case and cleaning cloth are included for storage and filter care.
