I purchased a cheaper ND/PL filter that beat these to the market and was so disappointed with the image quality. It was blurred and had terrible colors. This kit is well worth the upgrade. The included case holds ND8/PL, ND16/PL, ND32/PL, and ND64/PL that offer 3,4,5 and 6 stops of light reduction. The adjustable CPL filters to get rid of unwanted reflections are important to anyone who wears glasses.Pros:• Color accuracy and picture quality.• Threads to attach seem smoother than the first party version.• 3,4,5 and 6 stops of light reduction cover you from slightly bright Oct days to snowy reflective or summer scapes.• Each is a combo ND/PL so no need to stack.Cons: NA so far.

My wife and I took these K&F CONCEPT ND PL Filters on our recent hiking trip, and I have to say, they truly elevated our outdoor footage. We used the ND8, ND16, ND3, and ND64 filters, and each one performed wonderfully in different lighting conditions. The filters helped us control exposure, reduce glare, and capture crisp, professional-looking videos and photos—even under harsh sunlight and bright mountain skies. It’s like turning our ordinary hikes into cinematic adventures.What I appreciated most was the build quality. The HD optical glass is crystal clear, with multi-coating that effectively reduces reflections and enhances image clarity. The metal frames feel robust and durable—lightweight enough for easy handling, yet sturdy enough to withstand outdoor conditions. The quick-snap design made it effortless to swap filters on our Insta360 GO Ultra without missing a beat during our fast-paced hike.During our trek, these filters were put to the test in various scenarios—bright sunlight, shaded forest areas, and reflective water surfaces. Each time, the ND and PL filters delivered excellent results, balancing light and reducing excessive glare. The polarizing effect was especially noticeable when shooting reflections on lakes and wet rocks, giving our footage that polished, professional look. My wife kept saying, “Whoa, it’s like having perfect lighting every time!”The multi-coated optical glass ensures that our footage remains sharp without unnatural color shifts or dark spots. Whether we were capturing sweeping mountain views or close-up nature details, the footage stayed clear and vibrant. Plus, the filters are easy to clean—just wipe with a soft cloth, and they look brand new again. The additional benefits of durability and ease of use mean we’ll be bringing this kit along on all our future outdoor adventures.Overall, I am very satisfied with this filter kit. It’s a quality investment that truly enhances our outdoor videos and photos. For anyone looking to improve their outdoor filming experience with professional-grade filters—whether you’re a hobbyist or a semi-pro—these K&F CONCEPT filters are a must-have. They turned our simple hike into a cinematic masterpiece, and I can’t wait to see what we record next!

Neutral Density (ND) filters cut down the amount of light reaching the sensor. Used primarily in sunlight, ND filters help avoid overexposed skies. They can also be used to create flowing water effects and smooth motion suuch as passing cars and walking or running people.Circular Polarizer (CPL) filters are used to reduce reflections off surfaces like glass and water. They also help make colors appear richer.These clever filters combine ND and CPL functions in a single filter.These filters measure about 1.25 inches across, substantially larger than the GO Ultra lens. This makes it a little bit easier to rotate the ring that controls the degree of polarization.The ND8/PL, ND16/PL, ND32/PL, and ND64/PL filters offer 3,4,5 and 6 stops of light reduction. They are screw-in filters and require you to remove the original filter on the camera, which is easy to do.Overall, this is a really nicex set of filters and might well be considered essential by many videographers and photographers.Jerry

The set includes ND8, ND16, ND32, and ND64 filters, plus a polarizer that rotates smoothly. Each lens replaces the original one easily, and the ND filters are considerably larger than the stock lens but don’t tint or distort the footage. The lens type is printed on the side, which makes it easy to tell them apart. It also comes with a cleaning cloth and a sturdy plastic case, and everything arrived in perfect condition.The listing mentions water resistance, but I’d still stick with the original Insta360 lens cover for underwater shots. This set feels more suited for enhancing footage quality and creative control rather than being a daily or full-time lens replacement.

K&F Concept never disappoints, and this ND/PL filter kit for the Insta360 Go Ultra is no exception. The filters are well-machined, easy to attach, and feel like quality pieces of gear right out of the box. They’re a bit larger than the stock lens, but that’s expected—and honestly, the fit and finish make up for it.Accidentally gave one an impromptu “durability test” (aka dropped it on my concrete driveway), and to my surprise, it came out without a single scratch. Can’t speak to the water resistance yet, but that’s a great start for build quality.As for video quality, these filters make a real difference. The footage looks noticeably smoother and more cinematic—better motion blur, richer contrast, and more natural color without needing to crank on heavy color grading later. My reference clip at 2.7K/120p, ISO 100, 1/240 using the ND8/PL looked clean and balanced right out of the Insta360 app, just slowed down for effect.Overall, these are great ND/PL filters from a reputable brand—excellent clarity, smart design, and rugged enough to handle a real-world “oops” moment. Highly recommend for anyone looking to get pro-looking footage out of such a tiny camera.

So I grabbed this K&F Concept ND/PL filter kit for my Insta360 Go Ultra mostly because I’ve been doing more outdoor filming—hikes, snowboarding, even just walks under the blazing sun—and I needed something to handle that overly bright, washed-out look. Honestly, I didn’t expect much because the price isn’t crazy high, but it kinda surprised me right out the gate.The kit comes with four filters: ND8/PL, ND16/PL, ND32/PL, and ND64/PL. Basically, they each cut light by different amounts while also acting like polarizers, which is clutch for reducing reflections off water or snow and making skies pop a bit more. I slapped the ND16/PL on during a mid-day shoot in a wide-open park, and wow—the difference in motion blur and contrast was noticeable right away. It didn’t feel so flat and overexposed anymore. The sky had a nice deep blue tone, and the glare off puddles was toned down just enough without making it look fake.Build-wise, these feel pretty premium for what they cost. They’re made of AGC optical glass and have this multi-layer nano-coating thing going on, which I guess helps with clarity and scratch resistance. I didn’t baby them either—one slipped out of my bag and hit the pavement (heart attack moment), but not even a scratch. They’re also water-repellent, and I tested that by accident during a drizzly shoot. A few droplets rolled right off the lens like nothing happened.What I really appreciate is the screw-on design. No janky push-fit nonsense that feels like it’ll fall off mid-shoot. Once it’s on, it’s solid. Even during movement-heavy stuff like biking or running, it stayed put and didn’t mess with the camera’s stabilization. That said, switching filters out in the middle of shooting can be a little clunky—especially with cold fingers. Definitely not ideal when you’re in a rush.Now, I did notice a tiny bit of color shift with the ND64/PL, especially when the sun was hitting just right. It wasn’t a dealbreaker, and I was able to tweak it in post, but still something to keep in mind if you’re picky about color accuracy straight out of the cam. Also, if you’re filming with super wide angles, there’s a slight risk of vignetting at the corners, though I only noticed it with certain lighting setups.Overall though, for the price, this filter kit is a solid win. You get real ND/PL performance, it protects your lens, and the image quality boost is worth it—especially when you’re filming in harsh light or on reflective surfaces. If you’re not trying to spend a fortune on filters but still want your Insta360 footage to look more polished and cinematic, this is a smart pickup. I’ve been using it regularly and honestly don’t see myself shooting without it anymore.Would definitely recommend for anyone doing action shots, travel vlogs, or just outdoor filming in general.

I already had ND filters from K&F for my Action4, they did excellent work there and they are now also doing that on my Go Ultra, which has replaced Action4 by the way =)

Clear purchase recommendation, the option with the integrated PL filters in particular is worth its weight in gold. By turning, the PL filter is set stronger or less stronger.

I’m really impressed with this K&F Concept filter kit. The build quality is top-notch — solid metal frames and crystal-clear glass with no color distortion. They snap onto my Insta360 Go Ultra perfectly and feel very secure.The ND/PL combo works great for reducing glare and controlling exposure, especially when shooting outdoors in bright light. The image quality looks much smoother and more cinematic now — colors are richer and highlights are controlled.The set includes a good range of ND levels, so it’s easy to adjust depending on lighting conditions. Plus, the compact case keeps them safe and easy to carry.If into action videography or want to take your Insta360 footage to the next level, this filter kit is definitely worth it!

These filters are great for my Insta360. They clip on easily and are well fixed once in place. The range of filters are great with a noticeable difference and great for all light settings, even dim light. The build quality is what you'd expect from K&F and I'm happy overall.
