Filters as advertised!!! Will be ordering a second set for second camera.

ND4, ND8, ND16, and a polarized filter.This combo pack has a nice variety to help your Hero 4K get the best shot.Each lens has an aluminum frame that gives them a very quality feel. They also attach as securely as the OEM lens.A great set. You can't go wrong!(Remember... these are ONLY for the little Hero 4k camera and won't fit any other gopro).

Perfect fit on my GoPro 4K Hero. Quickly installs with just a twist on and off. The set comes with 4 filters. I tried all 4 filters plus the lens that came with the original camera and the ND16 did give me a little polarization when I took a picture of a bright, sunshine day as well as photos of the pond behind my house. I was actually hoping to see a little more of a difference with the polarization, especially when taking photos of the water. I have uploaded a picture with the original lens and then with the ND16 lens and while you can see some difference, again not what I thought it would have been. Each lens in between was closer to the original. Perhaps video, which would capture then sun rays bouncing off the lens would make more of a difference. I also did not put it underwater to see how it performs that way. Overall though I am pretty satisfied, and for the protection of having spare lenses, should something happen to the original it is worth it.

These ND filters work as advertised! They don't feel too cheap and the container to store them in is pretty nice as well. I'm sure these are almost as good as the more expensive ones.

I'm impressed with these.Form:These come in a nice foam-lined polyethylene storage case. Packaging is minimal, which I love. The case is the packaging.You get one circular polarizer and 3 ND filters of increasing darkness. I guess with the CP filter, you have to pick 1 of 2 ways it can be clocked on the mount and hope that works to cut the reflections you are trying to cut... perhaps you could play around and leave the filter partially installed if you needed to.When I first pulled one of these out I was blown away at the build quality. These strike me as on par with any high-end photography filter. All-aluminum body. They are notably bigger than the stock GoPro lens cover, not sure if that's a pro or con. If you're using your camera with a shell, you'd need some extra room in there.The seal that mates to the camera body is much bigger than the GoPro one, so I suspect it will work better. After using this camera in salt water with the stock lens cover, there are signs of corrosion around the lens mount. Clearly water was getting in there (by design???), but I suspect that wouldn't happen with these.These seem to do exactly what you'd want them to do, limit the light coming in. One thing I'm not too sure about is whether a camera that doesn't have any adjustability for exposure, EV compensation, aperture, ISO, whatsoever can benefit from an ND filter. I'll try to find a good light scenario and take comparison shots to update this with.

If you are looking for a way to enhance your GoPro's videos and photos, this filter assortment should cover just about any lighting and effect need you might have.

These filters are an excellent addition to any GoPro Hero 4K user's toolkit, offering a combination of enhanced functionality, stylish aesthetics, and solid construction.One of the first things I noticed about these filters is their exceptional build quality. They feel robust and well-made, inspiring confidence in their ability to withstand the demands of action camera use. They attach to the GoPro Hero 4K lens snugly and securely, with no wobbling or movement once installed. This ensures that the filters stay in place during even the most intense activities, providing consistent and reliable performance.These filters are particularly valuable for shooting in bright, snowy conditions, which can often overwhelm the camera's sensor and create washed-out footage. The filters effectively reduce glare and enhance contrast, allowing you to capture clearer and more visually appealing videos, even in challenging lighting environments. They help to balance the exposure and bring out the details in the snow, resulting in more dynamic and engaging footage.The filters also add a subtle tint to your videos, creating a cool and stylish aesthetic without distorting colors or affecting image quality. This can enhance the overall mood and atmosphere of your videos, adding a professional touch to your recordings.The price point of these filters is very reasonable, especially considering their quality and functionality. They offer a cost-effective way to expand your creative options and enhance the capabilities of your GoPro Hero 4K.Overall, these filters are a highly recommended accessory for any GoPro Hero 4K user. They provide a combination of practical benefits, such as glare reduction and contrast enhancement, along with a stylish aesthetic that can elevate your video footage. If you're looking to capture stunning videos in various lighting conditions and expand your creative options, these filters are an excellent investment.

The K&F brand makes very good products for photography and video. This kit of 4 filters is very well presented in a padded case that protects them perfectly on the go. The GoPro Hero 4K is a camera that is widely used in Drones for outdoor recordings where there is usually a lot of light and these filters help to obtain better images without being burned by excess sunlight.

They are essential if you record in broad daylight

The first thing I noticed with these filters is that they feel really solid and well built. They install snuggly and confidently, and don't move until you remove them. The GP 4K has very limited features as it is, and these filters help to add some versatility to your recording. With snow abounding everywhere where I live, these filters are great for handling the extra light and glare, while increasing some contrast with the scenery. The price point seems fair for what you are getting, and the tint of the lens adds a cool aesthetic touch, but does not discolor your recorded video. 5/5 stars.

Great filters and apparently the only ones on the market for this action cam right now!
