NiSi Filter UV Armor FX Pro Nano L395 40.5mm

NiSi Filter UV Armor FX Pro Nano L395 40.5mm – Explosion-proof lens protection with UV cutoff at 395nm

The NiSi Filter UV Armor FX Pro Nano L395 40.5mm gives your lens an explosion-proof protective layer while reducing UV interference below 395nm. It uses a laminated design adapted from high-end automobile windshields to avoid hazardous glass fragments and to protect the front element and lens coatings.

Key features and benefits

• Explosion-proof laminated design: Adopts the same laminated approach used in car windshields to prevent shattering into loose fragments.
• Safety for your lens: Constructed to avoid glass fragment formation, minimizing the risk of scratches to the front element and lens coatings.
• UV protection: Absorbs ultraviolet light with wavelengths below 395nm to improve image clarity by reducing UV-light interference.
• High transmission and low reflections: Double-sided nano coatings provide multi low-reflection properties and a 99% transmittance rate, minimizing glare and ghosting artifacts.
• Durable surface treatments: Coatings are double-sided waterproof and oil-proof, which helps protect the lens from dust and damage and makes the filter easier to clean.
• CINE optical glass: Uses high-quality CINE optical glass designed to maintain sharpness with no loss of resolution.
• Frame design and handling: Unique twill brass frame with a patented two-color design, making it easy to install and remove. The ultra-slim 3.9 mm frame features knurling for a secure grip.
• No vignetting on wide-angle lenses: Designed to avoid vignetting even on wide-angle lenses, including at 14mm (full frame).
• Front filter thread: Includes a front thread on the filter for added convenience when stacking or using additional accessories.

Use cases

Use this filter when you need both physical protection and optical performance. It protects cinema and photography lenses from impact and environmental contaminants. At the same time, it reduces UV interference and keeps contrast and clarity high thanks to its optical glass and coatings.

Practical notes

The Armor FX design originates from NiSi Explosion-Proof Cinema Filters and is widely used on high-end cinema lenses. You will find the filter easy to mount and remove because of its knurled slim frame and patented two-color design. In the field, the laminated construction helps keep shattered material contained after a strong impact, which lowers the chance of abrasive particles reaching your lens.

FAQ

Question: Will this filter cause vignetting on my wide-angle lens?
Answer: No. The NiSi Armor FX Pro Nano L395 is designed with an ultra-slim 3.9 mm frame that prevents vignetting on wide-angle lenses, including at 14mm on full-frame cameras.

Question: How does the explosion-proof design protect the lens?
Answer: The filter uses a laminated, explosion-proof construction adapted from automobile windshields. This design keeps the filter cracked but not shattered after a strong impact, avoiding loose glass fragments that could scratch the front element or coatings.

Question: How do the coatings affect cleaning and image quality?
Answer: The double-sided nano coatings provide multi low-reflection properties and a 99% transmittance rate, which reduces glare and ghosting. The same coatings are waterproof and oil-proof on both sides, making the filter super-easy to clean while helping to protect the lens from dust and fingerprints.

Question: Is this filter suitable for cinema lenses?
Answer: Yes. This Armor FX series is the original NiSi Explosion-Proof Cinema Filter design and is widely used for high-end cinema lenses. It combines CINE optical glass with protection and handling features tailored for professional use.
