have known the filters from "K&F Concept" for several years. I have already bought some filters for my DSLR camera that I have been using for years and I am still satisfied. ----------------------------------- The manufacturer's GoPro filters are also very well made. The frame is made of aircraft aluminum which has been manufactured using CNC technology. The glasses have several layers and have different strengths. On the small bayonet there is a rubber ring that prevents water from getting in. In this set there are the following filters:

The GoPro's 9 / 10 /11 already take really good pictures ex works, but with the help of ND/PL filters the pictures get even better. That's why I chose the set from K & F. The set was delivered in a storage box. The filters are simply offset to the left, then rotated slightly to the right and thus fixed. So a quick change is always possible. I use the ND/PL filters for photos and videos, whether for drones, system cameras and action cams. Because the colors come across more effectively and better. When it comes to ND/PL filters, I mostly use the ND8PL and ND16PL. ND32PL when it is extremely bright, in winter when it snows, on days with clear skies and clear sunshine. The ND64PL softens the fast movements in waterfalls and clouds, which comes across as silky. Everything else is razor sharp. It's best to try it yourself and then compare the results. The quality of the materials, including the glass, is impeccable and the processing of the filters is good. The attachment is easy and quick, they hold reliably, fit perfectly and the recordings are more professional. The PL filter minimizes mirroring and reflections. In addition, the images become more colorful and richer in contrast. Explanation of the ND filter: I use them for long-term exposure and depending on the sunlight. This allows you to take softer shots. What is a neutral density filter/ND filter? A neutral density filter is a filter where the glass is completely darkened so that less light can enter the lens. So it is possible to choose longer shutter speeds and to achieve the corresponding effects, such as foggy water or soft, long-drawn-out clouds. This would not be possible without a filter, as the image would be extremely overexposed or even completely white. About the neutral density filters: There are different variations of gray filters with confusing, different names from different manufacturers. I don't want to go into the different manufacturers here, just the different designations. I had to read through it first, but basically, it's easy to understand. The designations for this set mean: ND8 = slow down the shutter speed by 3 f-stops to increase the exposure time ND16 = slow down the shutter speed by 4 f-stops to increase the exposure time ND32 = slow down the shutter speed by 5 f-stops to increase the exposure time ND64 = slow down the shutter speed by 5 f-stops to increase the exposure time Shutter speed by 6 f-stops to increase the exposure time This allows outdoor scenes to be created very effectively and effectively. With the use of the various filters you will see how beneficial they actually are. Every professional works with such filters ;-) The polarization level can be adjusted with these ND/PL filters. I am very satisfied with this filter set and can clearly recommend it. Thank you for taking the time to read my review. I hope that I was able to help a little with this, also with the photos.

The filter set is supplied in a storage box with a foam insert. This is still in a box printed with the most important information, which is shrink-wrapped again for protection. On the 2nd picture you can also see the different tint levels of the individual lenses. In the video you can see that the CPL lens can be rotated without detent to adjust. On the last picture you can see that K&F has oriented itself to GoPro in terms of attachment and also relies on the proven bayonet lock via wire bracket. However, the housing of the individual lenses is not made of plastic, but of aluminum and, as can be seen in the 4th picture, even has cut-outs to make handling easier. The lenses are all printed for quick selection. Here, however, the alignment of the print triggers me. You can see on the 4th picture that the prints do not point in the same direction on the lens. All in all a very well made and valuable lens set for the GoPro.

TL; DR- Use the CPL filter most of the time and it's awesome. Fits my GoPro 9 perfectly and the storage case is actually quite good.

Even if the GoPro cameras take very good pictures with the basic equipment, in certain situations you can no longer get any further without the appropriate filters. The filter set from K&F Concept offers very good quality here. I've been a big friend of the K&F Concept filters for a long time. I've been using the filters from this manufacturer on my drone for a while now and I'm very happy with the results. The filters for the GoPro also absolutely impress me. The filters fit perfectly on the GoPro (hero 9 for me). They can be swapped out in seconds and are just as secure as the original GoPro glass. Since the filters are only slightly heavier than the original glass, there are no problems with using a gimbal. I really like the fact that this set directly combines ND and PL filters. So you have the combination of "sunglasses" and polarizing filter directly in one filter attachment. The filter is rotatable, so you can also adjust the direction of polarization. On bright summer days, or even in the snow, the filter set can be used to noticeably improve the recordings. As a rule, however, the ND8 or ND16 filter should be used in most cases. The two higher filter levels are primarily suitable for long exposures or in extreme sunshine. The optical quality of the filters is very good. There are no problems with distortion or other image disturbances. In terms of quality, there is absolutely nothing wrong with the K&F filters. Conclusion: A very good filter set at a reasonable price (currently around 70 euros). I can only recommend the filters from K&F Concept, I have never had any problems with this manufacturer. Definitely full 5 stars.

K&F Concept is a permanent guest with me, whether for my cameras or the GoPro. You can always use ND/PL filters anyway and in this quality anyway. The filters are super processed, present at just the right strengths for filming and help generate much more cinematic shots in broad daylight. Because we all know what happens when you film with an action cam with a shutter speed that is too short or when the camera even reaches its limits. Jerky and overexposed videos that look as if a cheap action cam was at work. And the GoPro can also be completely different, believe me! We use the GoPros on our FPV drones, i.e. the drones that you fly with such funny glasses. Here it happens extremely often that the exposure situation changes. And it's not a bad thing in itself if the camera regulates the whole thing automatically. But in order not to reach the limits of the camera in bright light, ND filters are also really useful here. And here we not only have ND filters, but even a combination of ND and PL filters. So the reflections can also say goodbye directly. Also especially cool when flying over water. In summary, the K&F Concept ND/PL filters are a great addition to camera and drone enthusiast's gear. The filters are of high quality and ensure more cinematic shots, especially in bright daylight. Glare and reflections can also be reduced thanks to the combination of ND and PL filters, which is particularly useful when flying or filming over water. Overall, the K&F Concept ND/PL filters are a worthwhile investment for anyone looking to take their recordings to the next level.

The high-quality filters come with a sturdy plastic box. They are made of metal and are very well made. No degree and turning the filter is very smooth. Each filter has a marking on the side that you can use to orientate yourself when turning. Each filter is also labeled on the side, so you can see very well which filter it is. The filters fit like a glove on the Gopro 11. I can recommend with a clear conscience.

I have owned and used other K&F camera products and this 4 pack lens filter is another quality product from them. The glass and filter frame construction are light and of high quality. The items that interested me the most were both the CPL and the ND8. The 2 special filters help me when I'm shooting into the sun and/or into the sun. It's something I've wanted for a while and I'm glad it's coming from K&F. Great Articles.

These aren't Tiffen filters I usually rely on for my DLSR gear, probably better. I am so excited to get this for my GoPro 11 Creators camera and Hero 11 Mini. K&F Concept has been consistently producing high-quality photo filters for years. They tend to have between 4.5 and 571 reviews on Adorama, a large user base that endorses the company and its products. The company continues to provide innovative solutions for GoPro and has received more than 150 patents and international awards. In addition, their photo travel bags are of unparalleled quality.

The GoPro is an excellent, versatile and almost indestructible camera. The robust market for third-party accessories makes it even better. You can already get every type of mount imaginable, but in recent years there has been an influx of filters and other lens modification accessories. This is particularly useful as it reduces reflections and glare that can obscure what you're actually trying to photograph. This is especially important for the GoPro, since you'll often use it on snow or water — both surfaces are prone to reflections. The four different filters offer light reduction options for all weather conditions (e.g.: ND8 for cloudy days, ND32 for sunny days) and are perfectly matched to the GoPro lens housing. If you use your GoPro outdoors at all - and I imagine most people do - these filters are essential. We recommend!
