The Insta360 Luna Ultra's 1-inch 8K sensor and Leica optics are wasted the moment you step into bright sun without a filter — the camera is forced to a fast shutter, and your video takes on that stuttery, over-sharp "security cam" look instead of smooth cinematic motion. A magnetic filter fixes it in two seconds. The two picks we trust most are Insta360's own: the ND Filter Set for controlling bright light, and the Black Mist Filter for a softer, filmic look. If you'd rather add a polarizer and a deeper ND range for less, the K&F Concept CPL + ND kit is the value option.
Here's the one rule that makes filters make sense on this camera: to get natural motion blur you want your shutter near double your frame rate (the "180-degree" rule — 1/50s at 25fps, 1/60s at 30fps). Outdoors that's impossible without cutting light, and that's exactly what a Neutral Density (ND) filter does. Everything else — diffusion, polarizer, UV — is about look and protection. Because the Luna Ultra takes magnetic filters, swapping is instant and there's no thread to cross.
Who this comparison is for#
- Luna Ultra owners who shoot outdoors and want smooth, cinematic motion instead of the choppy look you get from an uncontrolled shutter in daylight.
- Creators chasing a softer, more filmic image straight out of camera, without grading every clip.
- Anyone who wants one magnetic kit that covers bright sun, reflections and night shooting in a single pouch.
How we picked#
- ND first, because it's the one that changes your footage. The filter that actually matters day-to-day is ND — it's what lets you hold a cinematic shutter in daylight. We led with sets that cover the common brightness range.
- First-party fit and trust. Insta360's own filters are cut for the Luna Ultra's exact dual-lens front and colour-matched to its Leica profile, so there's no vignetting or colour cast to correct. That precision is why they're our top two.
- Magnetic, quick-release, stackable sanity. Every pick snaps on magnetically for tool-free swaps. We favoured ultra-slim frames that don't foul the gimbal and let you stow the camera with a filter still attached.
- Value without junk glass. For the all-in-one kit we wanted real optical glass with proper coatings, not the uncoated resin that adds flare and softness — the whole point of a filter is to improve the image, not degrade it.
Product 1 — Insta360 Luna Ultra ND Filter Set (Best Overall)#
This is the filter to buy first, full stop. Insta360's own set bundles the three ND strengths you actually reach for — ND4, ND16 and ND64 — covering everything from an overcast afternoon to harsh midday sun. Each one drops the light by a fixed number of stops so you can keep that cinematic shutter without blowing out the shot, and because it's the first-party set it's shaped for the Luna Ultra's exact dual-lens front with no vignetting and no colour shift to fix later.
The magnetic mount is the quiet win here: the filters snap on and off in a second, hold securely while the gimbal moves, and the frames are slim enough that you can pop the protective cover back on with a filter still attached. If you only buy one thing for this camera, buy this — it's the upgrade that makes daylight footage look like it was shot on purpose.
Key specs#
Type : Neutral Density set — ND4, ND16, ND64
Mount : Magnetic quick-release, first-party fit
Glass : Multi-coated optical glass, colour-matched to the Luna Ultra
Best for : Smooth cinematic motion in daylight
Bottom line. The single most useful filter buy for the Luna Ultra, and it's Insta360's own — perfect fit, no colour cast, three ND strengths that cover almost every outdoor situation.
Product 2 — Insta360 Luna Ultra Black Mist Filter (Best for a Cinematic Look)#
Where ND controls exposure, the Black Mist changes the mood. It's a 1/4-strength diffusion filter that gently blooms highlights, tames digital over-sharpness and lays a soft, filmic glow over the image — the look people spend hours trying to fake in editing, done in-camera and applied evenly across both of the Luna Ultra's lenses. It's especially flattering on skin and on any scene with bright points of light, like neon or a low sun.
Like the ND set, this is Insta360's first-party filter, so it seats precisely and magnetically with no fit or colour surprises. It's not a replacement for an ND — it doesn't cut enough light to fix daylight shutter on its own — but as the second filter in your bag it's the one that gives your footage character. Pair it with the ND set and you've covered both exposure and look.
Key specs#
Type : Black Mist 1/4 diffusion
Mount : Magnetic quick-release, first-party fit
Effect : Softens highlights, adds a subtle cinematic glow
Best for : A filmic look straight out of camera
Bottom line. The character filter. Won't replace an ND, but for a soft, cinematic image with no editing it's the best second buy — and it's Insta360's own, so the fit is exact.
Product 3 — K&F Concept CPL + ND Filter Kit (Best Value)#
If you want to add capabilities the two first-party filters don't cover without paying first-party prices, K&F Concept's kit is the value pick — and K&F is a respected filter specialist, not an anonymous brand. The kit bundles four magnetic filters: a CPL (polarizer) to cut reflections off water, glass and foliage, plus a strong ND range — ND16, ND64 and ND256 (4, 6 and 8 stops). The CPL is something neither Insta360 filter above offers, and the ND256 goes darker than the first-party set for very bright scenes or long-exposure looks.
The glass is properly made — K&F uses a multi-layer (28-layer) coating to keep colour cast and flare down — and the filters are ultra-slim and magnetic, so they snap on fast and you can even stow the camera with one attached. It's a third-party fit, so it's worth a quick check for any edge vignetting at the widest angle, but as a low-cost way to add a polarizer and a deeper ND range to your kit, it's hard to beat.
Key specs#
Type : 4-piece — CPL + ND16 + ND64 + ND256 (4/6/8-stop)
Mount : Magnetic quick-release, ultra-slim (third-party)
Glass : Multi-layer (28-layer) coated optical glass
Best for : Adding a polarizer and stronger ND for the least money
Bottom line. A respected filter brand's kit that adds a CPL and a deeper ND range the first-party set lacks, at a value price. The value pick.
Which one should you buy?#
Start with the Insta360 ND Filter Set — it's the filter that actually changes how your daylight footage looks, and being first-party it just works. Add the Insta360 Black Mist when you want that soft, cinematic character without touching the edit. Those two cover the vast majority of what the Luna Ultra needs, with the exact fit and colour matching only first-party filters guarantee.
Reach for the K&F Concept CPL + ND kit instead if you want a polarizer for reflections or a deeper ND range than the first-party set offers — it adds capabilities the Insta360 filters don't, from a respected filter brand at a value price. Whatever you choose, the magnetic mount means swapping filters mid-shoot takes seconds, so there's no reason to fight bright sun with a bare lens again.
FAQ#
Do I really need a filter for the Insta360 Luna Ultra? : For outdoor video, yes. Without an ND filter the camera raises its shutter speed in bright light, which removes natural motion blur and makes footage look choppy and over-sharp. An ND filter lets you keep a cinematic shutter, which is the single biggest change to how your video looks.
What's the difference between ND and Black Mist filters? : An ND (Neutral Density) filter simply cuts the amount of light so you can use a slower shutter in daylight — it's about exposure and motion. A Black Mist is a diffusion filter that softens highlights and adds a gentle glow — it's about look. They do different jobs, and many creators use both together.
Are Insta360's own filters worth more than a cheaper third-party kit? : If you value an exact fit and no colour cast, yes — first-party filters are cut for the Luna Ultra's dual-lens front and matched to its Leica colour, so there's nothing to correct. A third-party kit like K&F Concept's adds a polarizer and a deeper ND range for less money, at the cost of a little fit-and-colour precision. Buy first-party for your everyday ND and diffusion; add a kit if you want a CPL and stronger NDs affordably.
Will these filters block one of the Luna Ultra's two lenses? : No. Magnetic filters designed for the Luna Ultra cover the whole dual-lens front, so both lenses shoot through the filter evenly. That's part of why fit matters — a filter cut for a different camera can vignette or sit unevenly.
How do magnetic filters attach — do I need tools? : No tools. The filter snaps onto the magnetic mount on the front of the camera and holds firmly while the gimbal moves. Swapping filters mid-shoot takes a second, and slim frames let you refit the protective cover with a filter still on.
