Mavic 4 Pro ND Filter Sets Compared: Which One Should You Actually Buy?
Three brands, four kits, and one honest answer — the right set depends on the light you fly in, not the badge on the case.
You already know you need ND filters. Our guide to ND filters for the Mavic 4 Pro covers the 180-degree shutter rule and which strength suits which light. What that post deliberately skips is the part everyone actually gets stuck on: there are four or five kits on the shelf, they cost anywhere from twenty to a hundred and fifty dollars, and the marketing copy is identical.
So here is the practical version. The brand matters far less than people think. What matters is how many filters are in the set, whether they are polarised, and whether they are split.
The three things that actually differentiate a set
Count and range. A four-filter set covers most conditions. An eight-filter set covers all of them and doubles your options at each stop. The genuine question is whether you fly in enough different light to use eight, or whether four will live in your bag while you use two.
Polarised or not. An ND/PL combines neutral density with a circular polariser, which cuts reflected glare off water, glass, wet roads and foliage. It also costs you roughly a stop of light and, critically, the polarisation effect changes as you yaw the aircraft — a sky that looks beautifully deep flying north can go patchy flying east. That is a real problem in an orbit shot and the reason polarised filters are situational rather than default.
Split or uniform. Split filters are half one density and half another in a single element, so a bright sky and a darker foreground expose closer to each other. They are genuinely clever for horizon-heavy landscape work. They are useless — actively harmful — if your horizon is not roughly where the split is, which means most tracking and orbit footage.
Brand, honestly
| Brand | Where it sits | Worth paying for when |
|---|---|---|
| Freewell | The volume leader for DJI-specific kits. Widest range of Mavic 4 Pro sets. | You want a specific configuration — split, polarised, variable — and want it to fit correctly first time. |
| PolarPro | Premium. Better glass and coatings, notably better colour neutrality at the strong end. | You are grading in a colour-managed timeline and a filter-induced cast costs you real time. |
| K&F Concept | Budget. Perfectly usable optics; less consistent coatings and more variation between units. | You are unsure how much you will use them and want to find out cheaply. |
The uncomfortable truth: on a 1/1.3-inch tele sensor at 4K, the optical difference between a good budget filter and a premium one is difficult to see. On the 4/3 Hasselblad wide, shooting D-Log M and grading properly, it starts to show — mostly as a colour cast you have to correct rather than as softness. If you are shooting for yourself, buy the cheap set. If you are delivering to clients, the premium glass buys you time in post rather than resolution on the sensor.
Fit is the one thing you cannot compromise on.The Mavic 4 Pro’s mounting differs from previous Mavic generations, and a filter that seats imperfectly can catch during gimbal initialisation. Buy filters listed for the Mavic 4 Pro specifically — not “Mavic series” — regardless of brand.
What we would actually buy
If you buy one set and never think about it again
Freewell All Day 8-Pack (ND + ND/PL)
The set most Mavic 4 Pro pilots should buy first. Covers ND4 through ND64 plus polarised versions, which means you are never grounded waiting for the light to match your one filter.
This is the honest default recommendation. Eight filters is more than most people strictly need, but the alternative is discovering you are one stop short an hour into a shoot.

Freewell Split ND 4-Pack
Split filters — half ND8, half ND4 in a single element — so the bright sky and the darker ground expose closer to each other. A smaller, cheaper kit than the 8-pack if you mostly fly in even light.
Cheaper and lighter. The split design is a genuine advantage for horizon-heavy landscape work and a genuine disadvantage for orbits and tracking, so buy it knowing which kind of flying you do.

Freewell Bright Day 4-Pack (ND/PL)
Polarised throughout. Worth it if you shoot over water, glass, or wet roads, where glare rather than brightness is the thing ruining the shot.
Polarised throughout. Worth it over water, glass and wet roads. Remember the effect shifts as you rotate the aircraft — check your sky mid-orbit before you commit to a take.

Variable ND filters. They sound ideal — one filter, adjustable across several stops, no landing to swap. In practice, cheaper VNDs produce a cross-shaped darkening artefact at the strong end of their range, and even good ones stack two polarising elements in front of your lens with the colour-shift consequences that implies. For a drone, where you cannot see the artefact until you land, the risk outweighs the convenience.
UV filters. A film-era habit. Your sensor is not UV-sensitive in any way that matters, and you are adding glass in front of a Hasselblad lens for no optical gain.
ND1000 and similar extreme stops. Marketed for long-exposure work. A drone is a moving platform, so the long exposures these enable are mostly unusable unless you have landed the aircraft, at which point you would use a real camera.
Get the set home and then do this
- Fit each filter once, at your desk, and confirm it seats fully and the gimbal initialises cleanly with it on. Discovering a fit problem in a field is much worse.
- Label the case. In flat morning light with cold hands, ND16 and ND32 look identical.
- Shoot a test frame through each one against a neutral surface and check for colour cast. Now you know, before it matters.
- Put the whole thing in the drone bag permanently. A filter set at home is worth exactly nothing.
One thing worth flagging: filter cases are frequently magnetic, and a magnet in your launch area is a compass problem. Keep the case away from the aircraft while it powers up and acquires its heading — the reasoning is in our guide to compass errors and magnetic interference.
For everything else worth owning — and the accessories we think you can skip — see the gear page. If you would rather just have the strength chart in your pocket, that is what the filter set plus a printed reference card is for.
