Best ND Filters for Insta360 X4
The Insta360 X4 is dual 1/2-inch sensors, a locked F1.9, and ISO 100 as the floor. Video shutter runs from 1/8000 down to the frame-rate limit. In sun the body just shortens the shutter until 8K30 looks like a slideshow. The Standard Bundle ships Standard Lens Guards and no card — not ND. Insta360’s own page sells Motion ND in the app or Studio instead of glass. Official screw-on ND with Hall-sensor auto-detect is an X4 Air / X5 product. The 2026 kit that actually threads onto this barrel is the Freewell ND 4-Pack for Insta360 X4 (ND8 / ND16 / ND32 / ND64). It is not an X3 sticky rim, and it is not a CINSCAFD X4 Air filter.

Street prices move. Insta360’s ND factor table: ND8 = 3 stops, ND16 = 4, ND32 = 5, ND64 = 6, ND128 = 7. The 180-degree target is shutter ≈ 2× frame rate: ~1/60 at 8K30, ~1/120 at 5.7K60. ISO 100 is the floor — the camera cannot stop down F1.9. A pair of filters (one per lens). Do not stack over Lens Guards. Motion ND in Studio is a software blur; it does not write a slower shutter to the INSV.
How We Picked These Filters
- What Insta360 published for this body: X4 hardware sheet: dual 1/2-inch sensors, F1.9, 6.7 mm equivalent, minimum focus 0.6 m, safe stitch 0.8 m. Weight 203 g. 360 video: 8K 7680×3840 at 30/25/24, 5.7K at up to 60 fps, 4K 360 at up to 100 fps. Single-lens 4K60. ISO 100–6400. Shutter: photo 1/8000–120 s; video 1/8000 to the fps limit. I-Log 10-bit is on the shooting table. Waterproof 10 m without a Dive Case; Invisible Dive Case to 50 m. Standard Lens Guards in the box (align the mark, rotate clockwise to the mic). Premium Lens Guards sold separately. After install: enable Standard or Premium in Lens Guard Mode; Auto detects official guards; after removal set No Lens Guards or the stitch breaks. Lens Guards are not for underwater or rain. Store page: Standard Bundle is camera + Standard Lens Guards — no microSD, no ND. Product page: Motion ND in the app or Studio “without using an ND filter.”
- Why F1.9 still needs glass: Aperture does not move. ISO 100 is the floor. In sun the legal picture is a faster shutter, which kills 180-degree blur at 24/30/60. Insta360’s ND guide is sunglasses for the sensor and shutter ≈ 2× fps. ND16/32 is the weekday pair; ND64 is beach, snow, and noon (the same guide’s “extremely bright” step; ND128 is the next one — rare on X4 third-party kits). I-Log will show a cheap magenta/green cast. Motion ND is a grade, not a shutter. 8K30 does not unlock a different thread.
- The thread and the SKU traps: X4 Lens Guards are a screw-on that replaced X3 sticky rings. Third-party ND for this camera uses that same seat — one pair, one density, replacing the guards. Freewell’s live storefront now leads Luna Ultra / X6; the cart must print Insta360 X4 and four ND (retailers still say Standard Day or All-Day — All-Day on Freewell’s newer cameras means ND+ND/PL; do not buy Luna Ultra All Day). K&F’s X4 4-pack is the AGC / 28-layer class listing that says X4, not Ace Pro 2 FSI114 or Pocket magnets. TELESIN’s X4 3-pack is ND8/16/32; their One R / Ace / GO Ultra kits are other snaps. Official Insta360 ND: X5 summer note called those “the first ND filters designed for a 360 camera.” X-series ND manuals list X4 Air and X5 only — Hall sensor, on-screen density confirm, CINSCAFD-class SKUs. Those rims will not center on 2024 X4 glass. Same skip: X3 filters, 43 mm photo ND, stacking, water.
Best ND Filters for Insta360 X4: Detailed Reviews
Freewell ND 4-Pack for Insta360 X4 View on Amazon View on B&H
| Kit | Four ND, case, cloth. Retailers still label Standard Day or All-Day. Confirm four densities and X4 on the box. |
|---|---|
| Stops | 3 / 4 / 5 / 6 — Insta360’s own ND8–64 factor list |
| On X4 | 8K30 → aim ~1/60 · 5.7K60 → aim ~1/120 · ISO 100 · start at ND16 or ND32 in sun |
| Fit trap | Not X3 Standard Day, not One R, not Luna Ultra / X6, not X5 / X4 Air official ND |
| Guards | Remove Standard or Premium Lens Guards. Set No Lens Guards. The filter is the cover. |
Why it fits the X4. Insta360 never put physical ND in this bundle. Freewell’s four-stop recipe is the same daylight ladder their other Insta360 kits still ship. The useful part is the X4 thread, not a brand slide. These rims replace the official screw-on guards so the glass sits close to the bubbles — a fat stacked pair is how a black ring appears in Studio. Coatings are why this is Overall when you are grading I-Log: less magenta than a $20 three-pack. Freewell’s homepage now pushes Luna Ultra and X6; read the title. Gloves make swaps slow. That is a field tax, not a reason to buy a magnet that will not seat on this barrel.
Skip this if K&F X4 is a few dollars cheaper this week — same ND8–64. Skip it if you only shoot dusk interiors; you want Lens Guards, not ND. Skip Luna Ultra All Day (eight filters, different camera).
- ND8–64 covers Insta360’s published daylight ladder
- X4 screw-on, not a reused X3 sticky or One R snap
- Still the cleanest commonly stocked 2026 X4 kit
- Freewell’s storefront no longer leads with X4 — read the box
- No CPL in the four-ND kit

K&F Concept ND 4-Pack for Insta360 X4 View on Amazon View on B&H
| Kit | ND8, ND16, ND32, ND64, case. Aviation-alloy frames on current X4 listings. |
|---|---|
| Glass | K&F’s action-cam kits in this class: imported AGC, 28-layer nano / green-film coatings (water / scratch). |
| On X4 | Same 180-degree math as Overall. Expect a touch more warmth in I-Log than Freewell — white-balance in Studio. |
| SKU trap | Ace Pro 2 snap kits (FSI114). GO Ultra ND/PL. Pocket 3 magnets. 77 mm photo ND. “Works on X4 and X5” without two SKUs. |
Why it is Value, not Overall. Four useful daylight stops on the correct thread is the job. K&F usually undercuts Freewell for the same ND8–64. The frames can run a little thicker — that is a stitch-band argument, not a stop argument. Confirm the listing photo is two screw-on bubbles for X4, not a single Ace Pro rectangle. Do not buy a 14-filter K&F drawer and call it this page’s Value pick.
Skip this if Freewell X4 is within a few dollars — Overall. Skip if the cart says Ace, GO Ultra, or Pocket.
- Full ND8–64 at street prices under Freewell
- Named glass / coating class, not a no-name twin
- Amazon search also surfaces Ace / GO Ultra K&F
- Slightly warmer cast vs Freewell in snow

TELESIN ND 3-Pack for Insta360 X4 View on Amazon View on B&H
| Kit | Typical X4 box: ND8, ND16, ND32. Some listings add a CPL — that is extra, not a fourth ND. |
|---|---|
| Missing | ND64 (6 stops). Insta360’s sunny-day FAQ starts at ND64 / ND128 for “extremely bright.” |
| On X4 | Same thread as the official guards. Threading is often rougher than Freewell. Align the mark; do not cross-thread the barrel. |
| SKU trap | TELESIN One R ND8/16/32+CPL (B08C4ZZGMC-class). Ace Pro old-lens snaps. GO Ultra kits. |
Why it is Budget. Three correct weekday stops on the X4 seat is enough to learn 1/60 at 30 fps. You give up ND64, you give up Freewell coatings, and you accept more edge softness in an 8K stitch. For a family hike you will reframe in the phone app, that is enough. For paid 8K, it is not. If a TELESIN 4-pack that adds ND64 is in stock and still says X4, that is the better Budget cart — still not Overall.
Skip this if the outing is beach or snow — buy Freewell or K&F for the ND64. Skip every TELESIN box that prints One R or Ace.
- ND8/16/32 at entry money
- Screw-on X4, not a magnet
- No ND64 in the usual 3-pack
- Rougher thread, more CA than Freewell

If You Need Something Else
These two are not cheaper versions of the Top 3. One is a polarizer for glare. One is the official ND for a different camera that Amazon titles like “X4.”
CPL for Insta360 X4 View on Amazon View on B&H
| What it is | Circular polarizer on X4 screw-on rims (Sunnylife and similar). Cuts glare on water, glass, wet paint. It is not an ND stop. |
|---|---|
| 360 warning | A CPL polarizes from one sun angle. Two fisheyes can stitch a dark-blue half to a pale half if the rings do not match. Set both, then check the sphere. Safer in Single-Lens mode. |
| When it wins | Dashboard glass, surf, ski — after ND already holds 1/60 or 1/120 |
Do not stack a CPL on an ND on this thread. If the remaining problem is shutter, stay in the Top 3. If the remaining problem is a white lake, this is the layer. Insta360’s own ND guide still treats polarization as a different job.
Skip this if you do not shoot water or snow — Freewell or K&F is enough.

Insta360 X4 Air / X5 official ND View on Amazon View on B&H
| Why it shows up | Insta360’s store and Amazon title these “X4 Air ND16/32/64.” The old lens-filters page invented an “Official X4 ND Filter Set” for the 2024 camera. That kit is not on the X4 store page. |
|---|---|
| SKU | X4 Air: CINSCAFD-01 / -02 / -03 (ND16 / 32 / 64). X5 adds ND128 (red). Manuals: applicable models X4 Air and X5. Hall sensor; camera prompts you to confirm the density. |
| On original X4 | Wrong barrel. No Hall prompt. Will not seat like a Standard Lens Guard. X5’s summer note called official 360 ND “the first” — that is the later cameras. |
Motion ND in the X4 app is the first-party substitute Insta360 actually shipped for this body. It is a post effect. Buy third-party X4 screw-on glass if the INSV shutter has to be 1/60. Same skip: X6 Freewell, X3 sticky ND, 43 mm photo ND, variable ND, and any listing that says one SKU fits X4 and X5.
Skip this if the camera in the bag is an original X4. Buy Freewell X4, K&F X4, or TELESIN X4.

Frequently Asked Questions
What ND strength the X4 needs
F1.9 does not stop down. ISO 100 is the floor. Insta360’s ND guide: shutter ≈ 2× frame rate — about 1/60 at 30 fps, 1/120 at 60 fps. ND8 is 3 stops, ND16 is 4, ND32 is 5, ND64 is 6. Weekday sun is ND16 or ND32. Beach, snow, and noon are ND64 (the same guide’s “extremely bright” step). Indoors or night, take them off. If the frame goes dark, drop a stop; do not crank ISO first.
Official Insta360 ND on the original X4
No first-party physical set shipped for this body. The store bundle is camera + Standard Lens Guards. The product page points at Motion ND in the app or Studio. Official X-series ND manuals name X4 Air and X5 — Hall sensor, on-screen confirm, CINSCAFD-class filters. X5’s own note called those the first 360 ND. Amazon “X4 Air ND” is the wrong camera.
Lens Guards under the ND
No. X4 Standard and Premium guards occupy the same screw-on seat. Insta360: after you remove guards, set No Lens Guards or the stitch fails. Third-party ND is not Standard or Premium — leave the mode on No Lens Guards or Auto, then check the sphere in Studio. Do not stack. The filter is the sacrificial glass if the camera hits concrete.
Motion ND versus a physical filter
Motion ND is a software blur Insta360 applies in the app or Studio. It does not change the shutter stored in the INSV, and it does not save clipped 8K highlights the way ND16/32 does at ISO 100. Use it when you already shot without glass. Use a screw-on pair when you can set 1/60 or 1/120 before you press record. I-Log still wants neutral glass, not a cheap cast you fight in color.
ND in water or rain
X4 is rated 10 m without a Dive Case. Insta360: Lens Guards are not for underwater or rain; dry them if they fog. X-series ND manuals: filters are not fully sealed — no surfing, no rain. Same rule for third-party X4 ND. For 360 in water, use the official Invisible Dive Case (50 m) and take the filters off. ND does not fix refraction on two fisheyes.
Final Verdict
For most Insta360 X4 kits, buy the Freewell X4 ND 4-pack, unscrew the Standard Lens Guards, set No Lens Guards, and start at ND16 or ND32 until 8K30 sits near 1/60 (or 5.7K60 near 1/120). F1.9 does not stop down. ISO 100 is the floor. Insta360 never shipped physical ND for this camera — Motion ND is software, and official X4 Air / X5 filters are a different barrel. Same four stops for less? K&F X4. Trying ND? TELESIN’s 3-pack. Glare after shutter is solved? An X4 CPL. Skip X3 glass, skip stacking, skip rain. This page is the original X4, not X4 Air.
