dont often write reviews but I had to do this one because I used to think K&F glass was poor quality because they tend to be cheaper. I was wrong, If you’re buying any K&F filter, You gotta buy the Nano X Series. It’s fantastic Glass. When I got my Fujifilm 23mm F2 Lens i wanted to cover it to prevent scratches and possible breakage as this is my daily camera and it takes a beating hanging and swinging from my neck all day. I saw the Fusion One Next Protector From Hoya, the reviews were good and the price was high, I believed it was best, but while using it i could see the glaring in low light like a thin layer of white over photos. Yes it’s not enough to ruin a photo but if you care about details you’ll notice the difference. I have other Nano-X mist filters and NDs so i decided to try this one. I did a test in a controlled lighting environment in manual settings to test both uv filters and the K&F nano X came out cleaner with the glare. It fits well note, the purpose of this is to protect my lens, nothing else. I’ve included photos from the test but i doubt you’ll be able to see it as the quality will drop from uploading.

needed a UV filter for one of my Sony lenses, so decided to order this K&F Concept 67mm UV filter, mainly for protection of my expensive lens. I really like the side grips on this filter as it lets me screw on or take off the filter very easily. I also find the glass to be very clear, and I don't notice any part of my image being degraded at all. The threads are a little rougher than I am used to on this filter as it didn't screw on as smoothly as I am used to, but that also means it won't fall off easily either. Overall, I am quite satisfied with this filter and have no fear it will give me the protection and image quality I am looking for.

got this to help with lens protection on a telephoto zoom lens. Have been using it for 24hrs in this glorious winters sun light and have had no issues with pictures I have taken. Need to give it a full workout, but based on prior experience with this make and this level of coating, I'm not expecting any big / medium issues. Looking forward to using further.

This filter is really very transparent, to the point that when you take it out of its round, plastic case, you'd think there was only one ring. Only in good light and depending on the orientation can you see some colored reflections. The coating is really very good, probably on par with the nano I don't know what treatment, but effective. So much so that I tested it by taking pictures with a strong white light source to check, and if I lose nothing in sharpness (very good point), I gain in reflection management, although the gain is subtle, but noticeable (low tilt = with filter, pronounced tilt = without filter): the glare on the right is a little attenuated. More in-depth tests at sea for example would allow us to get a better idea of the qualities of this filter, but there are already visible qualities. In addition, it fits very well on my limited optics (no vignetting perceived with the more advanced lens hood for the time being). It will also protect against small dust particles, small grains, splashes, etc. without any loss of quality. This filter offers excellent value for money.

Really well machined filter with good quality, crystal clear glass. The lens filter screws onto my lens (Sigma 24-70mm) easily and still allows for use of the lens hood and the lens cap. A UV filter will protect your lens from dust and dirt and can help reduce surface reflection and some colour casting in sunlight. The filter comes with a great protective carry case so when not in use it's well protected (and looks good) Great addition to my kit bag.

like this company they offer high quality at a moderate price equals great value. Don’t make the mistake of putting cheap stuff on your nice camera, these are highly recommended

UV filter should offer protection and not impact the image at all. So far, it’s been doing just that. No complaints. My camera is usually on auto white balance so any shift is being corrected in camera. It’s also very transparent and difficult to tell that there is a filter in front of the lens. It’s also easy to remove and put on.
