Viltrox Ultra Slim MC UV Filter - Lens Protection with B270 Glass

The Viltrox Ultra Slim MC UV filter offers high transparency, absorbs UV rays, and reduces blue tones caused by UV, ensuring clarity and faithful color reproduction in images. Keeping the filter on the lens effectively protects the front element from dust, scratches, and impacts — a sacrificial surface much cheaper to replace than the lens.

B270 Ultra HD Optical Glass
The filter is made from professional-grade B270 optical glass, with high hardness (9H) resistant to scratches. Light transmission is 99.5%, with an extremely low reflectivity of 0.3% — for clear images and faithful color reproduction, without light loss or extra flare.

18 Nano-Coating Layers
Both sides of the filter feature 18 layers of nano-coating with multiple properties:

• Hydrophobic: water slides off the surface, easy to clean
• Antistatic: attracts less dust
• Oil-resistant: fingerprints erase easily
• Scratch-resistant: durable protection of the optical surface

Ultra-Slim CNC Aluminum Frame
The frame is made from aircraft-grade aluminum alloy, ultra-precisely CNC machined, and rust-resistant. With a thickness of only 3.2mm, the ultra-slim design can be used without problems on wide-angle lenses — without vignetting (dark corners) even at wide focal lengths.

How to Choose the Correct Diameter
The filter diameter must match the lens thread diameter. This value is printed on the lens or front cap, accompanied by the symbol Ø (e.g., Ø67 means a 67mm thread). Choose the filter variant with the same diameter.

Why Use a Protective UV Filter
The UV filter serves a dual purpose: it filters ultraviolet rays (reducing atmospheric haze and blue tones, especially at high distances or near the sea) and, more importantly for modern digital cameras, it naturally protects the front element of the lens. A scratch or impact on the filter means replacing an economical filter, not the entire lens. The filter remains permanently mounted as a protective layer.
