NiSi Filter UV Armor FX Pro Nano L395 49mm

NiSi Filter UV Armor FX Pro Nano L395 49mm – Explosion-proof UV protection for your lens

Explosion-proof laminated construction for lens safety

The NiSi Armor FX Pro Nano L395 uses an explosion-proof laminated design modeled after high-end automobile front windshields. This construction prevents the formation of loose glass fragments when the filter receives a strong impact. As a result, the risk of scratches to the front element and lens coatings decreases because broken glass remains bonded rather than shattering into pieces.

Optical performance and UV absorption

This UV filter absorbs ultraviolet light with wavelengths below 395 nm (L395), which reduces UV interference and helps improve image clarity. In addition, the filter uses high-quality CINE optical glass and NiSi states that it produces no loss of sharpness. The double-sided nano coatings provide multi low-reflection protection and deliver a measured 99% transmittance rate, which minimizes glare and ghosting artifacts in your images.

Durable, easy-to-use surface treatments

The filter’s double-sided nano coatings make the surface water- and oil-repellent, which protects the glass from dust and simplifies cleaning. Because the coatings reduce surface contamination and resist oils, you can clean the filter more quickly and maintain image quality with less effort.

Practical frame design and handling

The Armor FX series uses a unique twill brass frame with a patented two-color design that makes installation and removal straightforward. The frame is ultra-slim at 3.9 mm and includes knurling for an improved grip. For convenience, the filter has a front filter thread so you can attach additional filters or accessories. The slim profile avoids vignetting on wide-angle lenses, including at 14mm on full-frame cameras.

Professional use and origins

This is NiSi’s original explosion-proof cinema filter design, a solution widely used for high-end cinema lenses. The combination of protective construction, optical performance, and practical frame features makes the filter suitable for use in a wide range of shooting situations where lens protection and image clarity are important.

Smart FAQ

question: Will this filter affect my image sharpness?
Answer: NiSi specifies that the Armor FX Pro Nano L395 uses CINE optical glass and produces no loss of sharpness, so image detail should be preserved when you use the filter.

question: How does the explosion-proof design protect my lens in practice?
Answer: The filter employs a laminated construction that keeps cracked glass bonded rather than allowing it to shatter into loose fragments. Therefore, if the filter suffers a strong impact, it minimizes the chance that glass fragments will scratch the front element or lens coatings.

question: Is the filter easy to clean and maintain during shoots?
Answer: Yes. The double-sided nano coatings are waterproof and oil-proof, which reduces residue and makes cleaning quicker and easier. NiSi also describes the filter as super-easy to clean.

question: Can I attach accessories to the filter or stack other filters?
Answer: The filter includes a front filter thread for added convenience, so you can mount compatible accessories or additional front-threaded filters as needed.

question: Will this filter cause vignetting on wide-angle lenses?
Answer: The ultra-slim 3.9 mm frame is designed to avoid vignetting on wide-angle lenses, and NiSi states it does not cause vignetting even at 14mm on full-frame cameras.
