tested the ND/PL kit. The filters are delivered protected in a storage box. The attachment is very easy thanks to the bayonet lock. The filters fit perfectly and firmly on the camera - I use the GoPro Hero 11. The processing of the filters is impeccable and the price is therefore justified. I've been pretty happy with my no-filter shots so far, but these filters really add value to the shots. Thanks to the 4 filter strengths, you always have the right one for every exposure situation. The polarization is a perfect help with glare and reflections - I already knew that from my polarized sunglasses. With the use of filters, special effects are also possible - eg intentional blurred motion due to longer exposures, which would always lead to overexposure without filters. Conclusion: If you want to exploit the possibilities of your Hero 9/10/11 even more, this filter set is of very good quality, so I give it 5 stars and a purchase recommendation.

Hello dear friends, it's Berta again from Berta's Reviews. Today I'm rating "lens filter"

have probably 20 reviews on different filters from this company. I don't think I've ever had a reason to write a bad review either. I don't have any calls here either. These clearly use the same high quality optical material. It's just a different form factor, this case for a GoPro. The filters are of the excellent quality I have come to expect from K&F Concept, so they didn't make the materials cheap just because the filters were a different shape and smaller. I bought one of those kids that give you about 100 things for your action camera and it comes with some filters. You can just hold them up to a light and see the difference in quality between these and the ones that came with this kit. They're so much better. I find that for an action camera you need a neutral density filter even more when shooting video in very bright leaf-lit areas. It lets you open your aperture if you want a shower in depth of field, and lower the frame rate if you need that. These are different than a polarizing filter if you're just worried about glare, though. If your problem isn't glare, but simply too much light all around, then opt for a neutral density filter. Luckily, this kit includes three stops of neutral density apertures starting at 1/8 and also gives you a circular polarizing filter to eliminate that glare. The filters fit the GoPro perfectly so I don't have to worry about losing one and great optical quality. I would say such a kit is absolutely essential if you own an action camera. I'm not sure if the value for money for this set can be beat anywhere else.

Most people with an interest in photography will immediately recognize the K&F Concept name as a maker of quality photographic gear, and these GoPro lens filters are no different. High quality multi-coated optics are used in both the CPL and ND filters. With this lens set, you get three ND filters (ND stands for Neutral Density — more on that in a minute) and a circular polarizing filter. The CPL filter is a circular polarizing lens filter. These are used to reduce glare in your videos and photos. It also helps bring out the deep blue of the sky when shooting the sky, clouds, etc. You can rotate the front of the CPL lens, which is a great feature as it lets you see in real time what effect it is having on your color as you rotate it. The ND or neutral density filters basically act as "sunglasses" for your camera's lens and sensor. They're available in 8, 16, and 32 level reductions, giving you plenty of variety and choice. A fairly typical use of an ND filter would be photographing a waterfall. You want the classic image of a static landscape BUT with the water showing movement and flow. In order to achieve this, one would have to deliberately overexpose the shot to give the water movement. However, in doing so, everything else in the image (except for the waterfall) is blown out and overexposed until it's almost entirely white! Now when you put an ND filter on the lens, you force the shutter to stay open longer, resulting in a perfectly exposed image with the flowing water in the waterfall. This is a great lens set to have in your GoPro gear bag. One person found this information helpful

We were allowed to test the item ND/PL filter sets in connection with Vine. The ND/PL filter sets from the K&F Concept have certainly been well received. They are also compatible with GoPro Hero11/Hero10/Hero9 Black and are waterproof. Stable and unbreakable and make a good impression for use on the cam.

I'm not a big star photographer and I use the GoPro almost exclusively for underwater shots. Here other filters are required and these are then not attached to the camera but to the housing. So thank you very much for letting me test the set of ND/PL filters. Unfortunately, not every weather situation was possible, a snow picture is still pending. I tried out the filters individually and also - in order to have a better comparison - left the subject and the light influence as the same as possible. There is a rough recommendation of the individual filter strengths for the different light intensities, but I can only recommend trying out the filters. Twilight shots look even more intense. Especially with the 64 I like to try it out. The filters are neatly packaged and protected in a well usable case. For my part, a great addition for standard use, conclusion: 5 stars

These are great filters with exceptional build quality and fit. Fits the same or better than the original GoPro clear sleeve. All 4 had good scratch resistance and hydrophobic properties. I agree with other reviewers that the polarizer strength is low, but it worked well for my purposes in removing lake surface glare while kayaking.
