NiSi Filter UV SMC L395 67mm – Ultra-thin 3 mm frame and UV cut under 395NM
The NiSi UV SMC L395 67mm filter blocks UV light below 395NM while protecting your front element. It uses high-quality Japanese optical glass and double-sided multi-coating to keep images clear. The filter's aluminum frame is ultra-thin (3 mm) so it fits well on wide-angle lenses and helps avoid vignetting.
Key features
- Cuts UV-light under 395NM, reducing UV haze in images.
- Ultra-thin aluminum frame (only 3 mm) to minimize vignetting on wide-angle lenses.
- Double-sided, multi-coating on the optical surface for improved light transmission and reduced reflections.
- High-quality Japanese optical glass for high transmittance and a highly smooth surface.
- Hard waterproof and oil repellent coating on the outer side for easier cleaning and better resistance to contaminants.
- Protects the lens from dust and physical damage to the front element.
- Superfine dull polishing and elaborate knurling reduce visible wear and prevent the frame from blanching after repeated rotation.
- Front screw thread on the frame for easy installation of lens caps and other accessories.
- All materials meet European Union RoHS environmental protection standards and contain no hazardous substances.

Practical use and benefits
Use this filter to reduce UV haze in outdoor photography while keeping the image contrast and color fidelity high thanks to the coated Japanese glass. Because the frame is only 3 mm thick, it fits well on many wide-angle lenses and helps prevent vignetting. You also gain straightforward front protection for your lens against dust and minor impact.
Care and handling
The outer hard waterproof and oil repellent coating makes the filter easier to clean after use in humid or oily conditions. In addition, the superfine dull polishing and knurling on the frame reduce visible wear from repeated mounting and removal. Finally, the front screw thread allows you to attach lens caps or other accessories without removing the filter.
FAQ
Question: Will this NiSi filter cause vignetting on wide-angle lenses?
Answer: The filter uses an ultra-thin 3 mm aluminum frame specifically to minimize vignetting on wide-angle lenses, so it fits better on wider optics than thicker filters.
Question: How does the filter affect image quality?
Answer: The filter employs high-quality Japanese optical glass and double-sided multi-coating to maintain high transmittance (>98.3%) and low reflection (0.5%), which helps preserve image clarity and reduce unwanted reflections.
Question: Is the filter easy to maintain in outdoor conditions?
Answer: Yes. The outer surface has a hard waterproof and oil repellent coating, making it easier to clean and more resistant to water and fingerprints after use outdoors.
Question: Can I use a lens cap or screw-on accessories with the filter installed?
Answer: Yes. The frame includes a front screw thread to allow easy attachment of lens caps and other screw-on accessories without needing to remove the filter.
