Protection for 46mm DSLR Lenses

This K&F Concept C Series UV filter shields 46mm front threads from dirt, scratches and fingerprints while cutting ultraviolet haze. It is designed for any DSLR camera with a matching 46mm filter size. The slim 3.3mm frame avoids vignetting on wide-angle lenses. Keep it mounted permanently for continuous protection.

Optical Clarity and Light Transmission

Multi-coated, high-density German optical glass delivers 99.8% transmittance for minimal light loss. Anti-reflective layers reduce surface flare and improve contrast in outdoor scenes. Water- and oil-repellent coatings resist smudges and make cleaning easier. The thin aluminium ring adds negligible weight to the lens barrel.

Upgrade from Uncoated or Thicker Filters

Photographers using basic uncoated protectors will see clearer images and less ghosting with the multi-coated glass. The ultra-slim 3.3mm profile replaces bulkier rings that cause corner darkening on wide-angle zooms. It is not suited for shooters needing circular polarisation or neutral density effects. Buyers requiring a different thread diameter must choose the matching size.

Questions about this item

How do I install the 3.3mm ultra-slim filter without cross-threading the 46mm threads?

Align the CNC trapezoidal frame squarely with the lens threads, turn gently until it catches, then rotate smoothly; the non-slip knurl gives grip without forcing, preventing the cross-threading that happens when the thin ring is angled.

What maintenance will the multi-coated glass need over time?

The water- and oil-repellent coating resists fingerprints; when cleaning is needed, use a blower first, then a microfibre cloth with a drop of lens fluid — avoid paper tissues or dry wiping that can abrade the anti-reflective layers.

At what point does the 99.8% transmittance limit show up in sustained outdoor shooting?

The 99.8% figure means virtually no light loss, so the practical limit is not transmission but flare resistance; under strong, direct sunlight the multi-coating minimises ghosting, yet extreme backlighting can still produce veiling flare before the glass itself becomes the bottleneck.
