NiSi Filter UV SMC L395 72mm – Ultra-thin 3 mm UV filter that minimizes vignetting
This NiSi UV SMC L395 72mm filter blocks ultraviolet light below 395 nm while protecting your front lens element. It uses high-quality materials and surface treatments to deliver reliable optical performance and convenient handling for photographers and filmmakers.
Key features
- Ultra-thin aluminum frame with only 3 mm thickness to minimize vignetting on wide-angle lenses.
- Double-sided multi-coating to reduce reflections and preserve image quality.
- High-quality Japanese optical glass for high transmittance and a highly smooth surface.
- Protects the lens from dust and front-element damage during use and transport.
- Hard waterproof and oil-repellent coating on the outer side for easier cleaning and maintenance.
- Front screw thread on the frame for attaching a lens cap and other accessories.
Optical construction and performance
The filter employs Japanese optical glass and multi-layer coatings on both sides. As a result, it delivers very high light transmission and low surface reflection. Specifically, the glass achieves high transmittance and a highly smooth surface with low reflection, supporting accurate image capture while cutting UV light under 395 nm.
Frame design and handling
The frame uses a high-quality aluminum construction with an ultra-thin profile (3 mm). Therefore, the filter fits even on super wide-angle lenses to avoid vignetting and unwanted reflections. In addition, the frame receives superfine dull polishing and elaborate knurling. Consequently, repeated rotation will not blanch the finish, and you get secure, slip-resistant handling.
Durability, safety and maintenance
All materials used in this filter comply with the European Union's ROHS (Restrictions on Hazardous Substances) standard, which means they contain no hazardous substances as specified by that regulation. Furthermore, the outer surface features a hard waterproof and oil-repellent coating, so the filter is easy to clean and resists moisture and oily smudges. Overall, the filter protects your lens while remaining straightforward to maintain.

FAQ
Question: What does this filter block?
Answer: The NiSi UV SMC L395 cuts ultraviolet light under 395 nm, helping reduce UV haze while protecting the front element of your lens.
Question: Will this filter cause vignetting on wide-angle lenses?
Answer: The filter uses an ultra-thin 3 mm aluminum frame specifically to minimize vignetting, so it fits well even on super wide-angle lenses to avoid darkening at the corners.
Question: How is the filter constructed and finished?
Answer: It features high-quality Japanese optical glass with multi-coating on both sides, a superfine dull polish, and elaborate knurling on the frame to prevent blanching from repeated rotation.
Question: Is the filter easy to maintain and safe to use?
Answer: Yes. The outer side has a hard waterproof and oil-repellent coating that makes the filter easy to clean. In addition, all materials meet EU ROHS standards, meaning they contain no hazardous substances as defined by that regulation.
Question: Can I attach accessories to the filter?
Answer: Yes. The frame includes a front screw thread to make it easy to install a lens cap and other compatible accessories.
