Best Lens Filters for Insta360 X4
The Insta360 X4 is dual 1/2-inch sensors, a locked F1.9, and a Standard Bundle that ships Standard Lens Guards — not ND. The glass this body actually has an official mode for is the Premium Lens Guard. The old “official X4 ND set” on this page was the wrong camera.
Our Top Picks at a Glance
Paired to the 2024 X4 screw-on seat and Lens Guard Mode — not an X4 Air / X5 Hall-sensor ND list.
The only official glass for the 2024 X4 — tempered, twist-on, and the pair Lens Guard Mode was written for.

How We Picked
Three official facts decide the glass. Everything else is a pairing.
- The X4 hardware sheet lists dual 1/2-inch sensors, F1.9, 6.7 mm equivalent, 203 g, 8K30 / 5.7K60, and IPX8 to 10 m (Dive Case 50 m). Aperture does not stop down. There is no first-party density filter on that table.
- The Standard Bundle is camera + Standard Lens Guards, no card. Premium Lens Guards are the official tempered upgrade. Official X-series ND manuals name X4 Air and X5 — Hall sensor, on-screen confirm — not this 2024 barrel.
- The Lens Guards tutorial and accessories FAQ share one seat: Standard, Premium, No, or Auto. Guards are not for water, even in a Dive Case. Third-party glass is not a listed mode.

Insta360 X4 Premium Lens Guards (CINSBBMF) View on Amazon View on B&H
| Job | Tempered protector |
|---|---|
| Seat | Replaces Standard |
| Lens Guard Mode | Premium or Auto |
| Best for | Daily 8K stitch |
Insta360 never shipped a physical ND for this body. The glass it did ship as an upgrade is the Premium Lens Guard — and that is the filter the X4 actually knows how to stitch around.
The X4 Standard Bundle is the camera plus Standard Lens Guards. There is no microSD in that box and no ND. The upgrade Insta360 actually sells for this barrel is the X4 Premium Lens Guards (CINSBBMF): tempered glass, twist-on, X4 only, currently listed around $27.99. The accessories FAQ is blunt — Standard is the in-box pair for dust and everyday scratches; Premium is the separate tempered set “designed to preserve image quality,” and it is what they point at for maximum scratch resistance.
After they are on, swipe down and set Lens Guard Mode to Premium, or leave Auto if the pair comes on and off. Auto is the official advice when you swap often. Third-party ND and CPL sit on the same screw-on seat — they replace this glass, they do not stack on it. After any third-party rim goes on, the mode is No Lens Guards, because those rims are not Standard and not Premium.
The Lens Guards tutorial is the wet-use rule: guards are not designed for underwater use. Remove them and turn the mode off before the camera goes in water, even inside the Invisible Dive Case. The body itself is IPX8 to 10 m (Dive Case 50 m) on the hardware sheet. Dirty or worn guards affect the image; Insta360 also notes some glare with any guard in bright sun, and says the cleanest still is no guard at all when the shot is not rugged.
- Official X4 geometry — Standard / Premium / Auto modes exist for this pair
- Tempered replacement for the in-box Standard Guards
- Twist-off when the Invisible Dive Case goes on
- Not a density filter — F1.9 still dumps sun onto dual 1/2-inch sensors
- Not sealed; official tutorial says remove before water or rain
- Insta360 itself warns guards can add glare in bright light

Circular polarizer pair for Insta360 X4 View on Amazon View on B&H
| Job | Tempered protector |
|---|---|
| Seat | Replaces Standard |
| Lens Guard Mode | Premium or Auto |
| Best for | Daily 8K stitch |
A CPL is not another ND stop. It is the filter you buy when the X4’s 8K sphere is full of windshield and wet paint — and only after the shutter problem is already solved.
The X4 has two 1/2-inch sensors and a locked F1.9. A circular polarizer on that barrel kills glare on water, glass, and snow. It does not give you a 180-degree shutter at 8K30. That job is glass ND or Insta360’s Motion ND in the app or Studio (app export is capped at 4K60). Buy a pair printed for Insta360 X4 — not GO 3, not Ace, not Luna Ultra, not a 77 mm photo ring.
Unscrew the Standard or Premium Guards first. The CPL occupies that same seat. Set Lens Guard Mode to No Lens Guards. Match the rotation on both fisheyes, then open the sphere in Studio. A polarizer has one sun angle; two mismatched rings stitch a dark-blue half to a pale half. Single-Lens mode is the safer place if the sky must stay even.
Skip this if the problem is staccato 8K30 in noon sun. That is density, not polarization. Skip rain and surf — third-party rims are no more sealed than the official guards. Do not stack a CPL on a Premium Guard or on an ND.
- Does the glare job official Premium Guards cannot
- Same X4 screw-on seat — one pair, both lenses
- Useful in Single-Lens on glass and water after shutter is already held
- Two fisheyes can zebra the sky if the rings do not match
- Not an ND — locked F1.9 still needs density or Motion ND for 1/60 at 8K30
- Third-party: no Hall-sensor prompt, no official stitch profile

Insta360 X4 Standard Lens Guards (CINSBBME) View on Amazon View on B&H
| Job | In-box protector |
|---|---|
| Seat | Stock X4 thread |
| Lens Guard Mode | Standard or Auto |
| Best for | Spare / replacement |
The cheapest honest X4 filter is the one Insta360 already put in the box. A replacement CINSBBME pair is a spare, not a cinematic kit.
Insta360’s store copy for the Standard Bundle is specific: one X4 and one set of Standard Lens Guards. The tutorial repeats that the camera comes with Standard, and points at Premium only if you want the tempered upgrade. When the in-box pair is scuffed, the replacement SKU is CINSBBME — the same thread, the same Standard mode.
That is why this page no longer invents an “Official X4 ND Filter Set.” Official X-series ND manuals name X4 Air and X5, with Hall-sensor detect and on-screen density confirm. Those rims are a different barrel. Motion ND in the app is the first-party blur path on this 2024 body.
Keep a spare Standard pair in the pouch. Use Premium when the camera leaves the bag every day. Use a CPL when glare is the subject. Use a third-party X4 ND pack only when 8K30 needs a real shutter — that kit is a different shopping list.
- Official SKU, official Standard / Auto mode
- Same twist-on seat the camera shipped with
- Cheap spare when the box pair is already scratched
- Already in the Standard Bundle — do not buy a second pair on day one
- Not tempered Premium glass
- Same wet-use ban as Premium: off before water, even in a Dive Case

If You Need Something Else
X4 screw-on ND pack View on Amazon View on B&H
(typically ND8 / 16 / 32 / 64). Those rims replace the guards. They are not CINSBBMF and they are not the Hall-sensor X4 Air / X5 set. Set No Lens Guards, start around ND16 or ND32 for 8K30 in sun, and keep the official guards in the case.

Frequently Asked Questions
Why is there no official ND on this X4 page?
The 2024 X4 Standard Bundle is camera plus Standard Lens Guards. Official ND manuals list X4 Air and X5, with Hall-sensor detect. Motion ND in the app or Studio is the first-party blur path on this body. Physical stops are third-party rims on the guard thread.
Can ND or CPL stack on the Premium Lens Guards?
No. One screw-on seat. The filter replaces the guard. Stacking adds a ring the stitch was not profiled for. After a third-party rim, set No Lens Guards.
Which Lens Guard Mode does a third-party filter use?
No Lens Guards. Standard and Premium are official profiles. Auto detects official guards. A Freewell, K&F, Telesin, or CPL rim is none of those.
Do the Premium Guards stay on underwater?
Insta360’s tutorial says no — remove the guards and turn the mode off before water, even inside the Invisible Dive Case. The 10 m rating is the bare camera.
Why can a CPL split the 360 sky?
A polarizer has one sun angle. Two fisheyes that are not rotated the same stitch a dark half to a pale half. Match both rings, check the sphere, or use Single-Lens on glass.
Does Motion ND replace a filter?
It is a post effect in the Insta360 app and Studio. The app note supports media up to 4K60, and the on-screen preview is an approximation. It does not add density at capture and it does not protect the glass.
Will X4 Air or X5 ND filters fit this camera?
Those official ND rims are written for X4 Air and X5. This page is the April 2024 X4. Buy glass labeled for Insta360 X4, or buy CINSBBMF / CINSBBME.
Final Verdict
Buy the Premium Lens Guards if the X4 leaves the pouch — official tempered glass and a real Lens Guard Mode. Buy an X4 CPL pair when water, snow, or a windshield is the subject. Buy Standard Lens Guards only as a spare for the scratched box set. Need 1/60 at 8K30? That is a third-party ND pack or Motion ND, not another protector.
