I have to admit that I didn't buy the filter primarily as a UV filter, but rather as a protection for the lens. I was a bit skeptical because some other buyers wrote that the filter was scratched or dirty. I cannot confirm this. It was packaged well and securely, and thanks to the padding and plastic box, you can store it safely away when not in use. In terms of image technology, I didn't notice any real difference when taking pictures - but it has to be said that I'm not a professional. I didn't notice any vignetting either.

This is the second time I am using a UV filter and the reason I bought it was for my upcoming trip to Bali where I am planning a long photo shoot. Being in the wilderness and in a country with strong sun rays, I figured buying a new UV filter to protect my lens would be best. Well this is a K&F product as is my ND filter and tripod which I recently bought because that's how I am and I like to buy a lot from one company. It came very well packaged and feels like a really good quality and it fits perfectly. I am very happy with the product and look forward to using and abusing it.

Very nice filter to use. Every photographer can use it to expand their spectrum. If you are always looking for new impressions, you will find exactly what you are looking for here. Even on sunny days there is a lot going on with this! The image quality leaves nothing to be desired, the packaging is sensible and attractive, including a box for storage. The glass is well made, no scratches and high-quality framed.

Great price, I got it for the lens protector. The thickness is also good.

Economical UV filter I love making motorcycle videos and when I'm shooting on dirty roads I'm forced to use this type of filter to prevent a jumping rock from breaking my lens. Since they all produce UV rays, I leave you with a few photos where I've forced the appearance of the torch so you can see it clearly. Maybe it can be a problem for photos, but it looks cool in videos if you know how to play with it. The white has been yellowed a bit, giving the overall image a slightly warmer look. I hardly noticed any difference in sharpness between the filter on and off. For the price it is, it's great. I used to have one of the Hama brands and I would say this one is better.

Delivered in a plastic box that protects it well, the filter looks very nice and the polarization works well. I will also use it mounted on the lens to protect it. Useful and high quality

A dirty filter arrived, it wasn't just dust and after 10 minutes of cleaning with a special liquid and a lot of attention, it went away. I contacted the manufacturer and after a few days he replied and sent me a new filter to replace, recommended!

bought this filter to replace a damaged one. I had a good time and bought the same brand. The filter seems well made to me and the pleasant surprise of the knurling. I've always had the problem of not being able to grip when my hands are cold.

Admittedly, this filter comes at a very reasonable price. But on the other hand, it does its job perfectly. It protects the sensor from UV rays that burn the colors in the photos. You can see the result in my photos without retouching. I am completely satisfied. The blue sky isn't gray anymore, that's great.

bought this lens filter because I was looking for a filter no thicker than 3mm that would fit in a new Haoge lens hood (which cannot take thick filters) for my X100V to protect the lens and the camera to make weatherproof. If you don't know anything about the new X100V, you need a filter that is weatherproof. After some searching for a 3mm thick filter I found this filter from K&F Concepts on Amazon. I was skeptical that it would only cost £5.99 and there have been some complaints of a color cast. However, I thought I'd give it up for the price. The box it arrived in isn't the best, but it did its job and the filter arrived unmarked. I held it over a white surface and I could actually see a slight shade of brown. However, I don't see any color cast in the pictures. If you hold the filter up to the light you can see a purple reflection. I have tried to show this in the pictures but there is some fading. It looks very similar to the anti-reflective coating you have on glasses - I don't mind that. Overall I'm amazed, it's actually a really good filter with good spread and no obvious ghosting — I shot in the sun yesterday and it worked really well. I've bought far more expensive filters in the past that weren't as good. Recommended — consider buying a second one as a spare!
