NiSi Filter UV SMC L395 58mm – Ultra-thin 3 mm frame cuts UV below 395 nm
The NiSi Filter UV SMC L395 (58mm) blocks ultraviolet light below 395 nm while protecting your lens front element. Its ultra-thin aluminum frame measures only 3 mm, so the filter fits even on super wide-angle lenses and helps avoid vignetting and unwanted reflections.
Key features and benefits
This filter uses high-quality Japanese optical glass and a double-sided multi-coating to ensure excellent light transmission and low surface reflection. As a result, you keep image clarity while reducing UV haze in outdoor shooting. Additionally, the outer surface has a hard waterproof and oil-repellent coating that makes the filter easy to clean and maintain.
Furthermore, the frame receives superfine dull polishing and elaborate knurling. This treatment prevents the frame from blanching after repeated rotation. The front of the frame also includes a screw thread so you can mount a lens cap or other accessories directly.
What this filter offers
- Ultra thin, only 3 mm: Minimizes vignetting on wide-angle lenses
- Multi coating on both sides of the filter
- High quality optical glass for high transmittance (>98,3%) and highly smooth surface with low reflection (0,5%)
- Protects the lens from dust and damage to the front element
- Hard waterproof and oil repellent coating on outer side
- Easy to clean
Materials and compliance
The frame is made from high-quality aluminum. All materials used in this filter meet the European Union’s ROHS requirements, meaning they contain no hazardous substances covered by those restrictions.
Practical use cases
Use this UV filter when you shoot outdoors to reduce UV-related haze and to protect the front element of your lens. Because the frame is ultra-thin, you can attach it to wide-angle lenses without introducing vignetting. Also, the front screw thread lets you add a lens cap or other threaded accessories for convenience on set.
