K&F Concept 49mm UV Camera Filter

SKU CH-Y7DC-AKRG3

A 49mm UV filter using Japanese AGC glass with 28 multi-layer coatings for 99.6% light transmission and a 3.3mm ultra-slim frame to prevent vignetting

  • Size49 mm
  • Absorbs UV rays and reduces blue tones for clearer colour accuracy
  • 28 multi-layer coatings deliver 99.6% light transmission to minimise reflections
  • Japanese AGC optical glass preserves authentic colours with razor-sharp imagery
  • Ultra-slim 3.3mm frame prevents vignetting even on telephoto lenses
  • Hydrophobic and scratch-resistant coating protects the lens from dust and damage

Dual-purpose UV protection

This 49mm filter absorbs ultraviolet rays and reduces blue casts while shielding the front element from dust and scratches. It is built for photographers who want a permanent protective layer without sacrificing optical quality. The slim 3.3mm frame prevents vignetting on telephoto lenses.

Stepping up from basic glass

Replacing an uncoated or single-coated protector with this 28-layer NANOTEC design raises light transmission to 99.6% and cuts flare from both surfaces. The upgrade is worth it when shooting against bright skies or strong artificial light where ghosting would otherwise appear.

Thread-size constraint

The filter fits only lenses with a 49mm front thread, marked by the Ø49 symbol on the barrel. It cannot be used on larger or smaller diameters without a step ring, which adds thickness and may reintroduce vignetting. Verify the thread size before ordering.

Questions about this item

What lens thread size does this 49mm filter fit?

It fits any lens with a 49mm front thread, marked with the Ø49 symbol on the barrel or lens cap.

How do I install the filter without cross-threading the ultra-slim 3.3mm frame?

Align the filter squarely, turn gently until threads engage, then rotate clockwise until snug — do not force it, the thin ring strips easily.

How should I clean the 28-layer nano coating without damaging the hydrophobic surface?

Blow off dust first, then wipe with a clean microfibre cloth and a drop of lens fluid; avoid paper tissues or dry rubbing.
