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.
