It's my first ND filter and I was totally satisfied. Darkens the scene by 10 levels of light, allowing you to capture long exposure photos in full daylight in complete comfort. It's made of glass and looks good quality. I've used it with my Sony A6000 and haven't observed any dominant or aberration too appreciable. Comes with a leather case lined inside with a soft velvet fabric that is delivered very well so you can carry it without fear of scratches.

was happy to find this filter set for the GoPro 11 with its 3 different ND filters and a circular polarizer that actually rotates to get the best effect. It really isn't CPL in my book without the rotation feature, so I was glad this tiny CPL filter had that capability and was easy to adjust. I have a “mini” version but the filters fit both the mini and standard sized GoPro 11. The fit is identical to the original GoPro filter that comes pre-installed on the camera. Admittedly, I had to look for a way to remove the filter as I didn't want to break my new camera, but it turns out it's a simple twist of the filter 90 degrees to remove it. It requires a little strength, but that's better than being loose. The filters go back the same way, just pay attention to the two metal rods. It's obvious how to line them up once you see the clamp holding them. A set of ND filters can really open up some creative options, e.g. B. longer exposure times. A polarizing filter is a great way to remove reflections off water and glass, and to darken the sky for better color saturation. The construction of the filters themselves appears to be premium and feels premium. This filter set comes in a simple but very nice case that keeps all four filters safe. The box is about the same size as a regular single filter housing and doesn't take up much extra room in the camera bag. So where the GoPro is going, this filter set will go.

had actually used the K&F Concept ND filters for my DJI drones and GoPro for years and was always satisfied with them. Now I have received this from K&F for testing my new GoPro. Delivery was quick thanks to Amazon. The filters fit my old GoPro 10 and also my 11s. The filters from K&F Concept too, of course. There is not much difference in price between the two sets. K&F are about 5EUR cheaper. The filters are well made and sit firmly on the camera body. Even with a lot of action and turbulent scenes, there is no need to worry. The filters remain reliably in place. The exposure time is lengthened by the ND filters and the pictures simply look much better than without them. There are some good apps that recommend certain ND filters depending on location, time of year and position of the sun/time. Lens flares in backlit shots are also largely suppressed. The lenses are easy to clean and a case is included for transport. I can only recommend. I will use these ND filters for the GoPro 11 and my son will then get the GoPro 10 with the K&F Concept filters. :) How come? Because in detail, the K&F are a little better, especially with backlighting in the sun. But only minimally.

The K&F Concept ND/PL filter set is compatible with the GoPro Hero11, Hero10 and the Hero9 Black. The set of 4 includes three ND filters (8, 16 and 32) and a polarization filter. The workmanship is of high quality and the attachment is very quick. With the filter set you are actually equipped for almost all eventualities (regarding the influence of light and weather conditions). You can shoot great videos or take pictures that are much better in terms of quality, color and light play than without a filter.

I'm not ready to purchase an expensive 10 stop ND 100mm filter system yet. So I want to try this one out. The picture quality is solid for the money. Pic 1 (no filter), Pic 2(this product), Pic 3(K&F 40-1, 10 stop ND). Obviously, this is a big step up from plastic one (pic 3). In pic4, the pin holding the filter holder hinge was so loose. If you lose the pin, the filter holder become useless. The pin fell off when I first open the box. I didn't realize that until I tried to put the filter holder on my z6. Therefore, I decided to blue tape it to prevent the pin from falling out. I think it is a good buy if you are a amateur photographer.

This is tough to beat. Not only do you get a 100mm GLASS (not plastic) 10-stop ND filter, but you also get the filter METAL mount and multiple METAL lens adapters. Even if you need to buy step-up/down adapters because the ones included do not fit your lenses, this is still a bargain. Even though this comes in at well below the price of other 100mm 10-stop filters (without the mounting system), it performs excellently.

My unit doesn't produce any noticeable color cast, but I also shoot solely in RAW, so a color cast wouldn't be an issue anyway. The case for the filter is firm, so I don't worry about it very much when it's in my camera back, and the soft lining keeps the filter safe from scratches (so long as nothing coarse gets inside, of course). Better still, the filter mount features a second slot should you wish to use additional 100mm filters (e.g. graduated filters). I point out the size because this is the "standard" in these filters, rather than the more common 80-something mm ones you see in comparably-priced square ND filter bundles that use smaller, cheaper plastic filters instead.

The only issue I found, and this is really just nitpicking at this point, is that the filter mount never really feels very securely attached to the lens. The filter and mount won't fall off if the camera is moved or tilted forward, but the mechanism that attaches the mount to the lens adapter could be a bit tighter fitting in my opinion. Nevertheless, great product at a great price. Anything "better" will be considerably more expensive, and even then, how much "better" will it be?

am satisfied with these filters for my GoPro 10. I have not yet had the opportunity to test them well but for the little I have done I can say that they come in a practical package, are aesthetically beautiful and good are processed. I am happy! Great buy, especially given the fair price. Kit that a GoPro owner cannot miss

Excellent quality and works great with GoPro 10 Black.
