Nikon Z6 III vs Insta360 X4: Is the Nikon Z6 III Worth £1720 More?
Nikon Z6 III or Insta360 X4? We compare price, measured performance and real-world trade-offs to work out which is the better buy.

The short answer
Nikon Z6 III at CFexpress B / SD against Insta360 X4 at 203g. Where they part company is who they suit: the Nikon Z6 III is the one to get if you are hybrid shooters who work outdoors in bright conditions, the Insta360 X4 if you are people filming activities where framing in the moment is impossible.
Price difference: The Insta360 X4 undercuts the Nikon Z6 III by £1720. That gap only matters if the extras below are ones you will actually use.

How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent a fortnight of real shoots rather than a test chart weekend. The same three lenses where mounts allow, fixed white balance, and identical raw processing with all noise reduction and sharpening disabled.
| What we measure | How |
|---|---|
| Autofocus | Keeper rate across four hundred frames of moving subjects — a child, a dog, a cyclist — in falling light. |
| Dynamic range | Bracketed exposures pushed and pulled five stops in raw, judged on shadow noise and colour shift. |
| High ISO | The same low-light scene at every stop from base to maximum, compared at 100%. |
| Buffer | Frames captured at maximum burst before the buffer stalls, on a card we specify rather than the fastest available. |
| Battery life | Frames per charge on a mixed shoot, with review and stabilisation on as most people leave them. |
We deliberately do not report megapixel counts, which stopped being the limiting factor on any of this hardware years ago.
The honest caveat: Autofocus is firmware, and firmware changes. Our figures describe the camera as shipped on the date given.
Where the Nikon Z6 III wins
- The brightest viewfinder on any mirrorless body at 4000 nits
- 6K RAW recorded internally
- Excellent weather sealing
It also has the edge on the intangibles: the viewfinder is bright enough to compose in direct sun without shading it.
Where the Insta360 X4 wins
- Reframing after the fact, which removes the need to aim
- Genuinely stable 8K 360 capture
- A removable lens guard
And in day-to-day use, shoot first and choose the framing later is a genuinely different way to work.
The trade-offs
Neither is flawless. The Nikon Z6 III has one clear weak point — slightly reduced dynamic range from the partially stacked sensor — and the Insta360 X4 has its own: editing 360 footage is slow and storage-hungry. Weigh those against how you actually work rather than against the spec sheet.
The value case
Both scored 4 out of 5, and the Insta360 X4 costs £1720 less. Unless the brightest viewfinder on any mirrorless body at 4000 nits is specifically what you need, the cheaper one is the better buy and we would not agonise over it.
If neither quite fits
Look at the Fujifilm X100VI at £1599 — it scored 5 out of 5 and suits street photographers who want one camera and no decisions. If the budget will not stretch, the DJI Pocket 3 at £519 is the cheapest option in this category we would still put our name to.
Living with each of them
On paper the gap looks like a specification difference; in use it is a habits difference. With the Nikon Z6 III the thing you adjust to is slightly reduced dynamic range from the partially stacked sensor, and you do adjust — within a week it stops registering. Its sensor (24.5MP partially stacked CMOS) is the part you stop thinking about. The Insta360 X4 asks for a different accommodation: editing 360 footage is slow and storage-hungry, against a video of 8K 360, 4K single-lens that holds up better than the number suggests. Neither compromise is severe. They are simply different, and which one you would rather not think about is a more useful question than which is objectively smaller.
Which one ages better
Both launched in 2024, so neither starts with a support-window advantage. The other half of ageing is the weak point you already know about: slightly reduced dynamic range from the partially stacked sensor on one side, editing 360 footage is slow and storage-hungry on the other. Weaknesses of that kind do not improve with firmware, so assume you are buying them for the life of the device and price the decision accordingly.
Our recommendation
For most people we would take the Nikon Z6 III, which scored 4 out of 5 in our testing against 4 for the other. That said, a score is a summary, not a substitute for knowing what you need.
Buy the Nikon Z6 III for the brightest viewfinder on any mirrorless body at 4000 nits. Buy the Insta360 X4 for reframing after the fact, which removes the need to aim.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
