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!

bought 4 filters: 3 of 67mm and 1 of 77mm. They came in a nice packaging (carton + a polypropylene box) Visually they all look good. To my eyes there is no visible drop in image quality with this filter compared to. The product looks good. I would give this product 5 stars if I didn't have major complaints about the mechanical part. The 77mm is almost perfect mechanically - a good match for the lenses I've tested it with. The first 67mm filter didn't fit my Canon 24-105mm F4 lens as well as my Fujifilm 18-135mm - it was impossible to screw it in due to the friction - just couldn't get into the thread. The second 67mm was almost perfect - a bit narrower than the Hoya HMC filter but perfectly acceptable. The third 67mm filter is narrower than the second, but I was able to put it on. I have decided to return the first 67mm filter and will keep the other 3 (2 x 67mm and 1x 77mm). Still, my thought is - was it worth the experimentation? I don't know it. The basic Hoya HMC is twice the price but is mechanically perfect. From another perspective, you could buy two of these and keep the one that fits...

I bought this filter to protect my camera lens from dust and the elements. It fits my lens perfectly and comes in a protective plastic case. Very happy with the extra protection this filter provides for my camera lens.
