I purchased this filter from them and it’s my first ever filter so I am not sure how it is in comparison to other brands but so far, it has been good. The pictures came out clear and there were no glares or visual shadows while on outdoor sunny place. The material is good and sturdy. Glad that I gave them a shot and will continue to see if there is any difference from using with filter vs w/o filter.

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.
