Ultra-thin 58mm UV filter with multi-coated B270 glass

Viltrox

Viltrox Ultra Slim MC UV Protection Filter 58mm

SKU CH-SA37-5EKGV

An ultra-thin 58 mm UV filter with 18-layer multi-coating, 99.5 % light transmission and 0.3 % reflectivity to protect the front element while preserving optical clarity

  • Shields lens from UV haze and blue cast with superior protection
  • 5% light transmission via B270 optical glass preserves image clarity
  • Multi-coated surface resists scratches for consistent image quality
  • Repels water, dust and fingerprints to extend lens lifespan
  • 3% reflectivity cuts glare and light scattering across 420-700nm

Ultra-Slim 58mm UV Filter

The Viltrox Pro series filter threads onto any 58mm front thread, shielding the front element from ultraviolet light, dust, moisture and fingerprints. Its ultra-thin profile avoids vignetting on wide-angle lenses, making it suitable for photographers who want permanent protection without altering the lens’s field of view.

18-Layer Multi-Coating Benefits

Eighteen coating layers cut surface reflectivity to 0.3 percent and push average visible-light transmission to 99.5 percent between 420 and 700 nanometres. The waterproof, stain-resistant surface repels water drops and smudges, so cleaning is quicker and the risk of micro-scratches during routine wiping is reduced.

B270 Optical Glass Capacity

High-precision B270 glass maintains surface flatness and parallelism, preserving the resolving power of the lens behind it. The filter handles everyday environmental hazards and constant outdoor use, but it adds no optical correction, so it cannot compensate for chromatic aberration or sharpness limits inherent in the lens itself.

Questions about this item

How often will the 18-layer coating need replacement from regular cleaning?

The multi-coated surface provides scratch resistance for regular use, and the filter acts as a durable shield against dust and fingerprints to protect the lens beneath.

What is the first optical limit reached during extended shooting in bright conditions?

In the visible band of 420-700nm, average light transmittance reaches about 99%, preserving clarity and color fidelity without haze or blue cast.

Does the 0.3% surface reflectivity affect heat buildup on the lens barrel during all-day use?

The ultra-thin design with 99.5% light transmission minimises reflection and scattering, maintaining balanced color performance without adding thermal load.
