This K&F Concept ND filter set is a great addition to the DJI Osmo Nano and really improves video quality. The different filter strengths make it easy to shoot in bright conditions while keeping smooth, natural-looking motion.The glass quality is excellent with no noticeable color shift, and everything stays sharp. The filters fit perfectly, feel well made, and don’t affect stabilization. Simple, reliable, and very effective, great value for anyone wanting better-looking footage.

A great set of filters for the Osmo Nano.They make the colours so much richer and remove reflections in bright sunlight conditions. I'm still learning what filters perform the best in specific light conditions to get the best quality/desired effect.The filters fit on the camera very well and they’re very easy to attach and take off.All filters function exactly as I expected and I consider this set great value for money.

Good quality and perfect fitment for the Osmo Nano.

Perfect. Never disappointed with K&F

As you would expect from Amazon, the order was there within a day!

When unpacking, there were no noticeable “chemical processing odors.”



The K&F Concept 6-piece ND and CPL filter set for the DJI Osmo Nano impresses me across the board and has proven to be an extremely useful addition to video and action recordings in practice. The aluminum alloy filter frames are made right at first glance, very cleanly, lightweight, fit and can be easily assembled without playing or a wobbly seat.

In practical use, the ND filters from ND8 to ND256 show exactly what you would expect from them:
A reliable reduction in light incidence in different lighting conditions. Especially in sunny weather or during outdoor activities such as hiking, water sports or traveling, they enable significantly more controlled lighting and more natural motion blur in videos. The gradations are also sensibly selected and cover a very wide range of applications, from soft morning light to extremely bright daylight.

The CPL filter completes the set perfectly. Reflections on water surfaces or glass are visibly reduced, colors appear richer, contrasts clearer without appearing unnatural. Shades of blue and green in particular benefit from this, which is particularly noticeable when taking landscape and outdoor photos. I could not notice any color shifts or significant loss of sharpness during use.

The bottom line is a very sophisticated, high-quality filter set that is ideal for ambitious amateur filmmakers as well as for professional applications. Workmanship, optical quality and practicality are all right, which is why I can fully recommend the set.

The filters look high-quality and are also good in terms of filter performance. The polarizing filter is easy to rotate and filters reflections very well without developing edge shadowing. Overall, a great filter set.
The only downside is the much too big case: with the Osmo Nano, you already have a really small action cam and then you add an unnecessarily large filter pack! The dimensions of 10.5 x 10.5 x 2 cm result in a volume of more than 220 ml. Sunnylife makes this much better, here the four filters are delivered in a 6.5 cm x 6.5 x 1 cm small case, i.e. only around 42ml volume — around 25% of the size! That's why I pull off a star because the case is just so cumbersome.
PS: I had already complained about the size of the box with the K&F Concept 2-IN-1 True Color filter — the box here was already much too big for a 55mm filter

A quality set of filters for the DJI Osmo Nano, you get four: one CPL and three ND filters (8, 16 and 32). This is a great set of filters for people new to filming with the DJI Osmo Nano. The product is incredibly durable, easy to use (just rotate the ring on the filter). The product fits well and is easy to take on and off.The ND filters are specifically great for recording videos, as they reduce glare and limit the amount of light coming into the camera, which is really useful for brighter locations.The product is definitely of value. I would recommend it.

After a couple of days using this little ND set on the Osmo Nano at an event, I’m kinda amazed how much calmer my footage looks. The camera’s great, but without NDs it loves to crank the shutter and everything turns crunchy—especially at 60/120fps in daytime. With the ND8/16/32/64 in the pouch, I can keep shutter in the sweet spot and the motion blur looks… cinematic, not jittery. The set is made specifically for the Nano, and it actually fits like it was meant to be there—no weird gaps, no wobble, and I didn’t have to strip off my cage or fiddle with mounts to make it work.Screw-on install is straightforward—tiny threads, yes, but they bite cleanly and once it’s on, it stays on. I swapped between ND16 and ND32 during a windy seaside shoot and it never backed off or rattled loose, even with the camera bouncing on a chest mount. The ring is small (obviously—it’s a tiny camera), so swapping with gloves is a bit fiddly, but bare-handed it’s quick enough that I didn’t miss shots. The “perfect compatibility with most cases” claim wasn’t just marketing fluff in my experience; I left my low-profile cage on and everything still cleared fine.Image quality is the part I was watching for, and honestly—no funky color cast I could see in real-world clips. Skin tones stayed neutral, skies didn’t go weird cyan, and highlights didn’t pick up sparkle or ghosting. Sharpness felt unchanged, which is big on such a small lens. That lines up with what I’ve seen from this brand’s filters on bigger cameras—folks keep praising their coatings and color accuracy—and that gave me a bit more confidence taking these out for client stuff.The coatings help in annoying, practical ways too. These have that multi-layer nano thing going on, and water beads right off—salt spray wiped clean with a microfiber without smearing, and dust/oil didn’t cling like cheaper glass I’ve used. I still baby them (quick air puff before every swap), but they’re not precious. After two sandy beach days, no scratches, no rainbow streaks, no flare surprises shooting toward the sun.The four-stop spread is genuinely useful. ND8 is my “cloudy/late afternoon” default, ND16 handles typical bright daytime, ND32 saves me at high noon, and ND64 is the secret weapon when you’re on water or snow or trying to keep 1/120 under brutal sunlight. The official kit for the Nano only goes up to ND32 and costs more, so having ND64 in this pack has already paid for itself a couple of times when the sun came out swinging.Couple of quirks, nothing deal-breaking. The ring is so small that you’ll occasionally fat-finger the front glass swapping in a hurry—keep a cloth handy. Hydrophobic or not, big droplets still need a blot; don’t rub grit around. And while the thread feels secure, I’ve learned to start the turn gently so you don’t cross-thread when you’re rushing between takes. Normal tiny-filter stuff.Value-wise, it’s kind of a no-brainer. It’s purpose-built for the Osmo Nano, it gives you the whole ND8–ND64 range in one tidy kit, and it’s noticeably cheaper than the OEM set. Early buyer feedback on the listing looked upbeat too, which mirrors my experience so far. If you shoot the Nano outdoors—even casually—this is the first accessory I’d throw in the bag. Five stars without hesitation.Highly recommend! I hope this review helps someone out.

K&F Concept has launched a nice filter set for the DJI Nano. In addition to 3 gray filters (ND 8, 16 and 32), a pole filter is also included. The gray filters are used to maintain certain shutter speeds for filming, while the polarizing filter reduces reflections on non-metallic objects and thus ensures improved color saturation.

In my experience, the filters are very good in terms of quality and can also be easily screwed into the DJI Nano. Please unscrew the Nano lens protector first. I didn't recognize that directly and was a bit surprised at first. The fit is right and the polarizing filter can of course be adjusted by turning.

All filters from K&F Concept fulfill one important detail: they have a seal! This also preserves the sealing of the DJI Nano. The nano is therefore waterproof to a certain extent even with the filters, as advertised by the manufacturer.

The K&F Concept set receives 5 stars from me and a recommendation to buy. The optical quality is right, the filters have a seal and the set is currently cheap at less than 30 euros. There is also a cloth to clean the filters and a good case for the filter set. In my opinion, this was a complete success.

Managing exposure on such small sensors is always a technical challenge, especially when trying to comply with the 180-degree rule to achieve smooth movement in videos and avoid that annoying stroboscopic effect typical of fast electronic shutters. I therefore opted for this specific set because I needed a quick solution to modulate the incoming light when shooting outdoors with strong contrast, where the dynamic range of the camera is put to the test and the skies often tend to burn out.

The construction quality of the glass is immediately noticeable. I did several tests with the CPL to see how it managed reflections on glass surfaces and water, and the polarization is effective without introducing those strange chromatic dominants that sometimes afflict economic filters. On the contrary, I love how it manages to recover the blue of the sky without making it look artificial, an aesthetic rendering that sincerely struck me for its naturalness.

The screw fastening system is solid, although I must admit that the attachment requires a certain millimetric precision and, in situations of haste, I may hesitate for a second in fear of not having inserted the correct thread immediately. In practice, however, once tightened, they become one with the lens and do not affect stabilization or size in the least, allowing the camera to be used as if it were naked.

As far as ND is concerned, the optical density seems consistent with the stated values. Going from ND8 to ND32, I didn't notice a drop in sharpness at the edges, a fundamental detail when working in high definition. They do not distort the camera's performance, but they allow it to work in its optimal conditions, maintaining a clean and manageable image then in post-production.
