It is made from high quality materials and is built to last, ensuring it will be a valuable addition to your photography equipment for years to come. The K&F Concept Circular Polarizer CPL is also very easy to use. It simply screws onto the front of your lens and can be rotated to achieve the desired effect. The filter is also compatible with a wide range of lenses, making it a versatile addition to your camera bag. In terms of price, the K&F Concept Circular Polarizer CPL is very affordable compared to other CPL filters on the market. This makes it an excellent option for photographers and filmmakers who are just starting out and are looking for a quality CPL at a reasonable price. Overall, the K&F Concept Circular Polarizer CPL is an excellent product that offers a number of benefits for photographers and filmmakers. Its ability to reduce glare and reflections, high build quality and affordable price make it an excellent choice for anyone looking to enhance their images. If you are looking for a high quality CPL filter, the K&F Concept Circular Polarizer CPL is an excellent choice.

As the title suggests, I've currently had the option to try just one of the filters. Aluminum frame and looks well made and assembled. I reserve the 5th star (full satisfaction) for prolonged use and mainly to check the goodness of the lens (that it doesn't "tilt" or ruin like other views)

These are great little lenses. They polarize and rotate. This way you can make all your reflections disappear, or you can enhance them and make the reflections more like a mirror image.

Makes the GoPro footage look much more solid and the colors are more lifelike. I bought a lens cap at the same time and have been using it for a few weeks with no scratches or peeling of the film on the lens. For me it has completely replaced the original Gopro lens

I've been using a variety of Freeweel filters for a long time. And since I have now misused my GoPro 9 times to use it as a dashcam, a polarization filter was necessary because of the reflections of the interior. And one without ND. These work very well during the day, but in the evening or when it is very twilight, this no longer works. Therefore, it should be a pure CPL filter for this time, which is not as darkened as the others. That's exactly what I got. Works great. I would definitely recommend.

As with many K&F Concept products, the final quality is excellent. The special lens (UV) has an aluminum frame and fits the camera and feels the same as the original lens. It's reassuring to have an aftermarket product fitted that works as it should without putting you in situations where you need to be "careful".

I used it for my GoPro 9, it's worth every penny.

I've tested this filter on some wet surfaces and it certainly reduces reflections, making the overall look more to my liking. It also reduced glare from road surfaces again, producing a very beautiful image. I had my ISO set at 800, which was great with the protective clear filter that came with the camera, but I had to go back to the default setting of ISO 1600 to get the best results. Image/video colors are also slightly better and the sky is a deeper blue, which looks good too. All in all a real accessory for my Gro Pro hero 10 Black.

I really like this line of filters, they are my favorite filters

Great compact polarizing filter. The polarization quality is impeccable, the quality of the image is not degraded, as can sometimes be the case with cheap filters. The lens passed the test in front of an LCD screen. In order to attach the filter, the original lens protection has to be unscrewed, which requires some force the first time, but from then on it is as easy as changing the lens on a large camera. The filter sits perfectly tight on the Gopro, the wheel can be turned easily.
