NiSi Filter UV SMC L395 77mm – Ultra-thin 3 mm frame and UV cutoff under 395 nm
The NiSi Filter UV SMC L395 for 77mm lenses blocks UV light below 395 nm while protecting your front element. It uses high quality Japanese optical glass and a double-sided multi-coating to ensure high transmittance and low surface reflection. Additionally, the filter frame is made from high quality aluminum and measures just 3 mm in thinness, making it the thinnest frame claimed so far and suitable even for many super wide-angle lenses to reduce vignetting and reflections.
Design and materials
The filter glass features double-sided multi-coating to improve light transmission and reduce reflections. Moreover, superfine dull polishing and careful knurling on the frame keep the finish intact through repeated mounting and removal. All materials meet the European Union's ROHS environmental protection requirements, so the filter contains no hazardous substances.
Practical details and compatibility
Furthermore, the front of the frame includes a screw thread to accept a lens cap or other front-mounted accessories. This makes it easy to protect the filter when not in use or to stack compatible accessories.
Key features
- Ultra thin, only 3 mm: Minimize vignetting effect 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%)
- Protect the lens from dust, damage to the front element
- Hard waterproof and oil repellent coating on outer side
- Easy to clean
Below we expand on these points to help you decide if this filter fits your needs. First, the ultra-thin 3 mm frame reduces the chance of mechanical vignetting on wide focal lengths. Second, the double-sided multi-coating and high-transmittance Japanese glass work together to preserve image clarity and color transmission while keeping reflections low. Third, the outer side receives a hard waterproof and oil-repellent coating, so water and oils bead up and the surface stays easier to maintain. Finally, the frame’s knurling and superfine dull polish ensure reliable grip and lasting finish during repeated use.

FAQ
question: What does the NiSi UV SMC L395 filter do?
Answer: The filter blocks ultraviolet light below 395 nm, which helps reduce UV haze and can improve image clarity outdoors. At the same time it protects the front element of your lens from dust and physical contact.
question: Will this filter cause vignetting on wide-angle lenses?
Answer: Because the filter uses an ultra-thin 3 mm aluminum frame, it is designed to minimize vignetting on wide-angle lenses and super wide-angle optics. However, compatibility depends on your specific lens design and any additional stacked accessories.
question: How do I keep the filter clean?
Answer: The outer side has a hard waterproof and oil-repellent coating for easier cleaning. You should still use a blower, soft brush, or microfiber cloth and appropriate cleaning solution to remove dust and smudges without scratching the surface.
question: Can I use my existing lens cap and accessories with this filter?
Answer: Yes. The frame includes a front screw thread so you can attach a lens cap or compatible front-mounted accessories directly to the filter.
