For my Panasonic Lumix G lenses, I needed two "protective filters" so that rain and fingerprints can't damage the front lenses. There are different opinions on the net about the effect of UV filters, so I don't want to say anything more about it, but there is a blue-tinted coating on the K&F Concept Pro UV filter, the delivery condition is perfect and the packaging is (especially in view of the the price) can almost be described as luxurious. A first check does not reveal any adverse effects on the image quality, and the slim design means there are no shadows on the 12mm lens. Lens caps continue to fit securely, and the lens hood also fits the lens either way. I see the handy "teeth" on the outer edge of the frame as a big advantage - finally someone has thought along! Especially with the "slim" filters, it is sometimes rather tedious to get them off again after they have been screwed "safely". There are even tools that make this removal possible in the first place. But that's a thing of the past here, with this practical ribbing on the edge it's no longer a problem. At that price you can also have one or two of these filters with you in your camera bag and when the mud has splashed you can quickly put a clean one on - just perfect!

UV filters in the digital age only make sense to a limited extent. I mainly use this type of filter as a protective glass for the lens, so that I don't have to worry about damaging the lens even on the beach or during somewhat hectic photo shoots. The protective function is achieved very well with this filter. The processing is good, the glass is clear and without inclusions. The filter edge is thin enough that there is no vignetting. The blue coating is a bit annoying. If the sun hits the filter unfavorably from the side, a blue shimmer is produced on the photos. Of course that shouldn't be the case. However, this phenomenon only occurs at very specific angles to the sun. But the value for money is good, so ⭐️⭐️⭐️⭐️

I now have this amazing filter attached to my Olympus 60mm macro lens. The lens has no lens hood, a bad front cap and obviously no filter. This is now on board, along with a tidy front cap and third-party lens hood. 46mm is a little small and fiddly, but this one has a really good knurled ring that feels good in the hand. The thread is also very smooth and positive. The color balance is imperceptibly different, so it doesn't bother when shooting in well-lit close-ups. I love the improvement on this brilliant lens. ricky

It is a UV filter and like all filters of this type it serves more as a protection than anything else. Don't think that it will prevent flare or allow you to capture backlight in extreme conditions. Maybe you have a little more control over the cross lights, but I don't think it can replace a lampshade. Let's say if you put filters on expensive lenses it's already a success if it doesn't affect the images, and about it can I'm not complaining, on the contrary, it seems to me that the pictures are a little more contrasting and (for me) more pleasant. Very good thread. In short, staying in the real world, it's definitely a good filter, especially given the competitive price.

Surprisingly good for the price. Haven't noticed a negative effect in any situation. I use the filter as lens protection.

ran various tests under different lighting conditions. I didn't notice any chromatic changes or flair. Slim, light and the workmanship looks good. I suggest always using a UV filter, especially to protect the lens from dust, water and scratches. Given the price and first impressions I think this product is really good value for money. Amazon flawless as always in 1 day delivery. Recommended.

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...

High quality filter No distortion in my photos, which was not the case with the cheap filters tried before. I can just recommend her. Mikaël

Very well made and good value for money. But... Unfortunately I had to return this to the retailer as the filter was a bit too wide to accommodate a lens hood, which was a very necessary requirement. The retailer readily accepted the return and had a very good free system for doing so. Well done!

I was looking for a filter that would not be too expensive to mount in a case for the GoPro on the motorcycle. I've already lost a few filters due to the vibrations. This filter not only screws well and fits perfectly, but also surprised me with its quality. In the videos I get in 4K I don't see any distortions or aberrations or lack of sharpness... I recommend this brand.
