The K&F Concept 52mm UV lens filter with scratch resistant ultraviolet protection is a must for any photographer looking to protect their camera lens. Build quality seems to be solid and I didn't have any issues with fitment. I'm glad i discovered K&F Concept, 5 stars!

Excelente. Lo utilizo en mi tele Sigma 150-600 y funciona perfecto. No se nota nada en la imagen y se siente de excelente calidad.

Used this on safari in Africa with 300 - 600 mm Sigma telephoto for Canon. Only issue was that it was hard to unscrew at times and I had to eventually buy a filter wrench.

Just received today. It feels light, even a bit flimsy when I hold it in my hand. Nevertheless, it feels quite high quality. It seems to have a thinner glass substrate compared to the B+W filters I have. Given the 95mm size, I even have a feeling that the glass might warp under stress, although I know that's unlikely. I'm curious about the optical performance. In terms of price, this is unbeatable, what all other UV filters should cost. There's just no justification for seeing a UV at $200 or even $300. Selling a UV for $200-300 sounds to me like people want the money but don't want to work reasonably hard.
