Price/performance is top. I had no changes or restrictions when taking photos. Autofocus works perfectly for me.

just got a new lens, needed a 77mm filter to protect it. I'm not going to sit down and tell you that this glass is better than any other glass. I just got it and I'm not an optics expert. But I can tell you the packaging was beautiful, the filter housing - one of the nicest I've ever seen. It is circular in shape and holds filters of multiple sizes with grooves in an internal holder. So much nicer than the big chunky square filter boxes I have from other brands. But - the killer was the filter which was so thin - and that it has 2 areas that are knobby so you can grab it - while the rest is smooth - a really nice feature. Seems right at home on my Canon RF24-105/4 L IS USM. I didn't notice any difference in focus speed or aberration, but again, I'm not a lab. I'm pretty happy with this brand. I did not expect.

K&F only made a few versions of UV/1A filters and this one falls in the upper price range. The packaging is excellent and the glass material is very good. So far I haven't noticed any color changes. The design on the metal rim offers easy installation/removal unlike others that sometimes require a filter wrench. It might not be the best filter (price wise) but at 30eur it's well worth the money well spent protecting my glass which already costs over half a grand. I trust the products of this company and will buy them again.

The main purpose is lens protection without compromising image quality. This UV filter meets these requirements.

if you just want a protective lens cover. This is a high quality product that I will recommend. It screwed into the lens very smoothly. Coating looks good.

I don't know how to describe it, but this UV filter is shockingly clear. It's like it's not even there, but it's there, and it looks beautiful too. If you've ever seen the glass that Apple stores use for their stores, so be it (Apple uses special glass for all of its stores and headquarters that's remarkably clear). This filter is like that. Haven't had it long enough to see if it really withstands scratches, bumps, water etc. but just from the first feel it seems like it does what it says on the tin.

Product as described and of a quality you would expect from K&F Concept. I have no complaints about the product, was what I expected, fits the lens well and does not impede the correct reinstallation of the lens cap. Can be a bit more expensive than other brands but I think quality is more important than cost. Overall a great product, fits well, quality is great and a good investment if you want to protect your lens face.
