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 accurate color reproduction in images. Keeping the filter on the lens effectively protects the front lens from dust, scratches, and impacts, serving as a more economical protective layer than the lens itself.

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

18-Layer Nano Multicoating
Both sides of the filter feature 18 layers of nanocoating with multiple properties:

• Hydrophobic: Water slides off the surface, making cleaning easier
• Antistatic: Attracts less dust
• Oil-resistant: Fingerprints are easily removed
• Scratch-resistant: Durable protection of the optical layer

Ultra-Thin CNC Aluminum Frame
The frame is made from aviation-grade aluminum alloy, precisely CNC machined, and rust-resistant. With a thickness of just 3.2mm, the ultra-thin design can be used without issues on wide-angle lenses — with no vignetting even at wide focal lengths.

How to Choose the Correct Diameter
The diameter of the filter must match the diameter of your lens's female thread. This value is marked on the lens or the front cap, preceded by the symbol Ø (e.g., Ø67 means a 67mm thread). Select the filter variant with the same diameter.

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