Best Lens Filters for Insta360 X3
The Insta360 X3 will raise shutter speed until a sunny 5.7K clip looks like a slideshow. Dual F1.9 1/2-inch sensors, 5.7K at 30 fps or 4K at 60 fps — Insta360’s own ND guide still wants the 180-degree rule (shutter about 2× frame rate). The company never shipped first-party ND for this body. Official X4 Air / X5 / X6 filters will not seat. The 2026 kit that still matches the X3 rims is a Freewell Standard Day 4-pack: ND8, ND16, ND32, ND64, slim enough that the stitch line stays a software problem, not a metal ring in the sphere.

How We Picked These Filters
- What the X3 actually is: Insta360’s X3 sheet: dual 1/2-inch 48 MP sensors, F1.9, 5.7K 360 at 24/25/30 fps, 4K 360 at up to 60 fps, 3K at 100 fps. Waterproof to 10 m without a housing. There is no first-party ND on that page. Insta360’s 2026 ND explainer lists official filters for X5, X4, GO Ultra, GO 3S, and Ace Pro 2 — not X3. Buy glass cut for this barrel. X5 filters that “auto-detect” on a newer camera will not sit on these lenses.
- 180-degree shutter, not a vibe: Same Insta360 guide: an ND is sunglasses for the sensor; the video target is shutter ≈ 2× frame rate so motion blur looks natural instead of staccato. On X3 that is about 1/60 at 30 fps and 1/120 at 60 fps. In hard sun the camera would rather raise shutter than hold that pair. ND8 is three stops, ND16 four, ND32 five, ND64 six, ND128 seven (Insta360’s factor table). ND16/32 is the weekday kit; ND64/128 is beach, glacier, and high noon. Indoors or night, take them off.
- The stitch is a mechanical problem: Two ~180° fisheyes meet in a band. A fat rim, a stacked Lens Guard, or a 43 mm photo ND in a holder prints a black ring or a soft seam in Studio. Prioritize X3-labeled slim frames, a pair (one per lens), and a mount that stays on a stick — screw or tight snap, not a loose magnet. Do not stack ND over official sticky guards. Do not buy Luna Ultra / X6 Freewell kits for this body. Search titles without quotes; skip Generic twins that omit “X3.”
Best Lens Filters for Insta360 X3: Detailed Reviews
Freewell Standard Day 4-Pack for Insta360 X3 View on Amazon View on B&H
| Kit | Freewell Standard Day · four ND · case · cloth |
|---|---|
| Stops | 3 / 4 / 5 / 6 (ND8–64) — Insta360’s own factor list |
| On X3 | 30 fps → aim ~1/60 · 60 fps → aim ~1/120 · start at ND16 or ND32 in sun |
| Fit trap | Not One R 4K, not ONE RS, not X4/X5/X6, not Luna Ultra Standard Day |
| Guards | Remove official sticky Lens Guards before the rims go on |
Why it fits the X3. Freewell’s Standard Day recipe is the same four densities their newer Insta360 kits still ship: ND8 through ND64. On this camera that is the weekday range. The useful part is the barrel, not the brand slide. X3 lenses are not X5 replaceable glass and not a Luna gimbal pair. A listing that only says “Insta360” is a One R (ND4–32, different snap). Buy the title that says X3. Slim CNC rims are why this row sits above Neewer: the stitch band has less metal to see. Screw-on security matters on a 3 m invisible stick. Gloves make swaps slow; that is a field tax, not a reason to buy magnets that shed.
Skip this if you need ND128 at altitude — Skyreat’s fifth filter. Skip it if you only shoot dusk interiors; you want Lens Guards, not ND.
- ND8–64 covers Insta360’s published daylight ladder
- X3-specific rims, not a reused One R snap
- Still the cleanest commonly stocked 2026 X3 kit
- No ND128, no CPL
- Freewell’s storefront now pushes Luna / X6 — read the box

Skyreat ND Filter Set 5-Pack for Insta360 X3 View on Amazon View on B&H
| Kit | ND8, ND16, ND32, ND64, ND128 |
|---|---|
| On X3 | ND128 is Insta360’s “extremely bright / sunny” step — snow, water, noon |
| SKU trap | Skyreat’s live catalog is mostly Mini 3 / Osmo Action. The cart must say Insta360 X3. |
| Build | Lighter alloy/plastic than Freewell; expect a touch more warmth in white snow |
Why it fits the X3. The extra stop is the reason this row exists. Freewell Standard Day stops at ND64. Insta360’s filter math says ND128 lets through about 0.78% of the light — that is how you hold 1/120 at 60 fps when the beach is a mirror. You pay less and you accept a warmer cast that Studio white balance can move. You do not accept a Mini 3 Pro six-pack that will not touch these lenses.
Skip this if Freewell is within ~$10 and you never shoot snow — take the slimmer rims. Skip every Skyreat box that does not print X3.
- ND128 without a second purchase
- Lower street price than Standard Day
- Light on a long stick
- Brand’s homepage is drones now — / clone risk
- Warm shift vs Freewell in snow

Neewer ND Filter Kit for Insta360 X3 View on Amazon View on B&H
| Kit | Typically ND8, ND16, ND32, ND64 |
|---|---|
| Mount | Pressure / snap-on — check tension before a bike run |
| On X3 | Same 180-degree math; thicker rims can soften the stitch in Studio |
| Honest limit | Fringing on tree-vs-sky; tint you correct in the app |
Why it fits the X3. Neewer is how most people try ND without a $60 invoice. The densities are the right numbers. The frames are the compromise: a little more thickness in the overlap, coatings that flare sooner, a snap that is not a Freewell thread. For a family hike that you will reframe in the phone app, that is enough. For a client 5.7K stitch, it is not. Hydrophobic coating helps droplets; it does not replace a dive case (X3 is 10 m bare — refraction still wrecks 360 underwater).
Skip this if the stitch is the product. Buy Freewell. Skip no-name 10-packs that omit X3.
- Correct ND8–64 range for little money
- Doubles as a harder cover than bare glass
- Easy snap for travel
- Thicker rims, more CA in contrast
- Snap-on is weaker than a screw rim on a long stick

If You Need Something Else
These two are not cheaper versions of the Top 3. One is glare control. One is the official ND for a different camera.
Freewell All Day Kit for Insta360 X3 View on Amazon View on B&H
| Adds | CPL and/or ND1000-class long exposure — confirm the X3 All Day contents on the box |
|---|---|
| When it wins | Dashboard glass, surf, ski — polarization that software cannot invent |
| 360 warning | A CPL on two fisheyes can zebra the sky if the rings do not match. Set both, then check the sphere. |
All Day is the upgrade when Standard Day already solved shutter and the remaining problem is specular glare. It is not a reason to skip Standard Day on a first kit. Do not buy Luna Ultra All Day (eight filters, different camera). ND1000 is a timelapse tool, not a run-and-gun ND32.
Skip this if you do not shoot water or snow — Standard Day is enough.

Insta360 X5 / X6 official ND sets View on Amazon View on B&H
| Why they show up | Insta360’s store and blog now lead with X5 / X6 / Ace ND |
|---|---|
| X5 set | ND16 / 32 / 64 / 128 · camera detects the filter — X5 / X4 Air barrels |
| X6 set | Freewell and Insta360 X6 kits are a shorter, wider body |
Wrong glass on the right brand. X3 does not auto-detect ND. These rims will not center on 2022 barrels. Same skip: Freewell One R Standard Day (ND4–32), 43 mm photo ND, magnetic “universal 360” tiles, and any listing that says the filters work on X3 and X5 without two different SKUs.
Skip this if the camera in your bag is an X3. Buy Freewell Standard Day, Skyreat X3, or Neewer X3.

Frequently Asked Questions
Will official Insta360 ND work on X3?
No. Insta360’s current ND page names X5, X4, GO Ultra, GO 3S, and Ace Pro 2. X5 filters even prompt you to pick the density on-screen. That hardware is not this barrel. Buy an X3-labeled pair.
Can I leave Lens Guards under the ND?
Usually no. Official sticky guards add thickness in the stitch zone and most ND rims are cut to the bare bezel. Choose guards for trail abuse or ND for shutter. Do not stack.
What shutter should I set?
Insta360’s ND guide: about 2× the frame rate. 30 fps → ~1/60. 60 fps → ~1/120. Then pick ND until ISO stays low and highlights hold. If the image goes dark, drop a stop (ND32 → ND16), do not crank ISO first.
Do I need ND underwater?
Not as a substitute for a dive case. X3 is rated 10 m bare; water on two fisheyes is a refraction / stitch problem. ND does not fix that. Use the housing for 360 in water; use ND in air.
Final Verdict
For most X3 owners, buy the Freewell Standard Day 4-pack, pull the sticky guards, and start at ND16 or ND32 until 30 fps sits near 1/60 (or 60 fps near 1/120). Need ND128 at noon? Skyreat’s X3 five-pack. Trying ND for the first time? Neewer. Skip official X5/X6 ND, skip One R Freewell, skip anything that does not print X3 on the box. Insta360 never made first-party filters for this camera. The kit has to be cut for these two bubbles.
