NiSi Filter UV Armor FX Pro Nano L395 39mm

NiSi Filter UV Armor FX Pro Nano L395 39mm – Explosion-proof UV protection for your lens

The NiSi UV Armor FX Pro Nano L395 39mm combines an explosion-proof laminated design with UV filtration to protect your lens and improve image clarity. It uses NiSi’s cinema-grade construction to reduce the risk of front-element damage while maintaining optical performance.

Explosion-proof laminated construction

NiSi Armor FX adopts the explosion-proof laminated design used for high-end automobile front windshields. As a result, the filter can remain cracked without shattering after a strong impact. This construction prevents the formation of loose glass fragments and therefore minimizes the risk of scratches to the front element and lens coatings.

Frame and mechanical design

• Unique frame made of twill brass with a patented two-color design for easier installation and removal.
• Ultra-slim 3.9 mm frame thickness to reduce the chance of vignetting on wide-angle lenses.
• Knurling on the frame provides a reliable grip for quick mounting and removal.
• Includes a front filter thread for added convenience when stacking filters or attaching accessories.

Optical and coating performance

This UV filter absorbs ultraviolet light with wavelengths below 395 nm, which helps reduce UV interference and improve overall image clarity. The filter uses double-sided nano coatings with multi low-reflection treatment to minimize glare and ghosting artifacts. These coatings deliver a high transmittance rate of 99% and are designed to be both waterproof and oil-proof, making the surface easier to clean and maintain.

Glass quality and intended use

The Armor FX series uses CINE optical glass that preserves image sharpness. NiSi’s original explosion-proof cinema filter design is widely used for high-end cinema lenses, so this 39mm variant brings that same protection and optical approach to compatible stills and cinema lenses. The filter protects the lens when shooting in a variety of scenes and environments.

FAQ

Question: Will this filter cause vignetting on wide-angle lenses?
Answer: No. The ultra-slim 3.9 mm frame is designed to avoid vignetting on wide-angle lenses, and NiSi states it will not vignette even at 14mm (FF).

Question: How does the explosion-proof design protect my lens?
Answer: The laminated construction keeps the filter from shattering into loose glass fragments after a strong impact. That containment minimizes the risk of scratches and damage to the lens front element and coatings.

Question: Does the filter affect image sharpness or introduce glare?
Answer: NiSi uses CINE optical glass to preserve sharpness. Additionally, the double-sided nano coatings with multi low-reflection treatments aim to reduce glare and ghosting while providing 99% transmittance.

Question: Is the filter easy to keep clean in the field?
Answer: Yes. The double-sided nano coatings are waterproof and oil-proof, which makes the filter surface easier to clean and maintain during shoots.

Question: Can I stack other filters or accessories on the front?
Answer: Yes. The filter includes a front filter thread for added convenience when stacking filters or attaching accessories.

Question: What mechanical features help with mounting and handling?
Answer: The twill brass frame includes knurling for a secure grip and a patented two-color design to make installation and removal easier.
