I’ve been using this K&F CONCEPT ND/PL filter kit with my Insta360 Go Ultra for a few weeks now, and it’s really made a noticeable difference in my outdoor shots. The set covers everything from ND8 up to ND64, so whether I’m shooting bright beach scenes or sunlit hikes, I can dial in the right exposure without the footage looking blown out. The polarizing effect cuts glare nicely and boosts color contrast in skies and water, which makes the clips look way more professional straight out of the camera. Build quality feels solid — the metal frames are sturdy and the multi-coated glass seems scratch-resistant and clear, with no weird color cast. Installation is quick and snug, and once they’re on you hardly notice them. If you’re shooting a lot of outdoor action with the Go Ultra, this filter set is definitely worth grabbing — it opens up a lot more flexibility for bright conditions and smoother motion.

Love the K&F filters, and I have a few on different action type handheld mini cameras and a drone. They make a good difference in keeping the images in its best light (CPL) and keeping good frane rate and the ability to drop a few F Stops is handy when using the ND filters.With drones, it gives these cinematic type scenes. With cameras, better definition and deeper colors.I haven't tried this newer 'black mist" type filter, but that's next on my list. But having at least a CPL and 1 or 2 ND filters are a must have now.They are minimal weight and on/ off is a magnetic snap and they hold on well without lots of weight on the gimbal (but some - approx .08 grams on average).

Excellent Quality Filter Set!As with all my other K&F concept gear, this is made with top quality glass! This kit included the ND/PL line of filters that is a nice addition to my gear. Normally on an action camera like this I'm forced to choose one or the other for filters, a CPL or an ND filter, but this set has a cpl built into each ND filter making for a great combination! It is the best of both worlds, letting me knock down the glare, and capture the motion in one shot, saving me post work, as well as creating some fantastic images. The kit comes in a solid little plastic case that makes it easy to fit in my camera bag to have them with me and ready when I need them!

The Ultra is a great camera, but adding these ND filters makes it awesome—especially here in sunny Florida. The filters are well made and feel solid in the hand. The glass is clear and delivers excellent clarity. I have no issues with color shift; everything looks natural. The filters are really easy to install and fit extremely well—no fear of them coming loose. My only question is how they would hold up to serious abuse or a drop (they are on an action camera, after all). I don’t know yet. When I’m using these, I’m not putting the camera in intense situations, so it’s not really a complaint for me. Otherwise, these filters work great, fit great, and do exactly what an ND filter is supposed to do.

This K&F Concept ND/PL kit has been a solid match for my Insta360 Go Ultra. Outdoors, especially on bright afternoons at the park, the ND filters help tame harsh light so motion looks smoother and colors stay rich instead of blown out. The polarizing layer cuts glare off water and playground equipment, which keeps faces and skies more defined. Build quality feels premium with the metal frame and multi-coated glass; nothing flimsy, no haze, and it wipes clean easily after dusty outings with the kids. It looks a touch bulky at first glance, though once mounted it does not affect use or balance, so that ends up being purely cosmetic. Swapping between ND8, ND16, ND32, and ND64 is straightforward, and you can see the difference in footage immediately. For the results and durability, this set is worth the money.

The Nd/PL filter set was purchased to improve the Insta360 Go 3's image quality in bright lighting conditions by both controlling exposure and reducing reflections. The combination of both effects in one filter is a significant advantage for the compact action camera.
The optical performance of the filters is at a high level. There is no loss of sharpness and the color rendering remains largely neutral. The ND component makes it possible to increase the shutter speed in order to achieve natural motion blur even when the sun is shining. At the same time, the polarization component effectively eliminates reflections on non-metallic surfaces and visibly increases color saturation. The gradations from ND8 to ND64 cover the most common daylight scenarios well.

This is my first time using filters so don’t have a lot of experience or much to compare to. Basically the difference filters lower the level of light and glare the for the camera, like a pair of sunglasses. I found these filters easy to use and very effective when taking pictures with high exposure levels.

The filters come in a practical plastic box and are beautifully rubberized to prevent scratches. A small cleaning cloth is also included so that you can wipe it off before use so that no fingerprints are visible in the recording.
What I really like is that the ND filters are combined directly with a CPL filter, which is often only available separately so that you only have the choice of whether you want to use the 180 degree shutter rule or no annoying reflections, here both are combined and that with a good selection of ND filter strengths.
The filters are also really well made, the threads run like clockwork, they sit firmly on the camera and are really optimal.
Unfortunately, they are quite large, significantly larger than on the product images. Unfortunately, this somewhat nullifies the great form factor and inconspicuousness of the Go Ultra, even though I own the Go Ultra in black, which is why I also remove a star.
But since I am otherwise absolutely satisfied and like to use them for creative and great video projects, I give them 4 stars.

I've been using this filter kit for my action camera and I'm really impressed with the quality. The ease of use is fantastic; they screw on easily and stay secure during filming. I've noticed a big difference in the clarity of my shots, especially in bright conditions. These filters help reduce glare and enhance the colours beautifully, making my videos look much more professional.
