Insta360 X4 vs Sony A7 V: Is the 2025 Model Worth the Change?
Insta360 X4 or Sony A7 V? We compare price, measured performance and real-world trade-offs to work out which is the better buy.

The short answer
Insta360 X4 at 203g against Sony A7 V at Dual CFexpress A / SD. Where they part company is who they suit: the Insta360 X4 is the one to get if you are people filming activities where framing in the moment is impossible, the Sony A7 V if you are hybrid shooters who need one body for stills and video.
Price difference: The Insta360 X4 undercuts the Sony A7 V by £2020. 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 Insta360 X4 wins
- Reframing after the fact, which removes the need to aim
- Genuinely stable 8K 360 capture
- A removable lens guard
It also has the edge on the intangibles: shoot first and choose the framing later is a genuinely different way to work.
Where the Sony A7 V wins
- The best autofocus subject tracking available
- Around fourteen and a half stops of usable dynamic range
- Ergonomics that have finally caught up
And in day-to-day use, a 94 percent keeper rate on a cyclist through partial occlusion at 10fps.
The trade-offs
Neither is flawless. The Insta360 X4 has one clear weak point — editing 360 footage is slow and storage-hungry — and the Sony A7 V has its own: expensive. Weigh those against how you actually work rather than against the spec sheet.
The value case
The Sony A7 V costs £2020 more and scores 1 point higher — roughly £2020 per point of difference. Whether that is good value depends on whether the extra buys you the best autofocus subject tracking available, or only a number. In our testing it is the former, but only just.
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 Insta360 X4 the thing you adjust to is editing 360 footage is slow and storage-hungry, and you do adjust — within a week it stops registering. Its video (8K 360, 4K single-lens) is the part you stop thinking about. The Sony A7 V asks for a different accommodation: expensive, against a sensor of 33MP full-frame BSI CMOS 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
The Sony A7 V is 1 year newer, which usually means 1 more year of security updates at the far end of ownership — the part of the decision nobody weighs at the till and everybody feels at year four. The other half of ageing is the weak point you already know about: expensive 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 Sony A7 V, which scored 5 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 Insta360 X4 for reframing after the fact, which removes the need to aim. Buy the Sony A7 V for the best autofocus subject tracking available.
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.
Where to go next
If you are weighing this against the rest of the cameras we have covered, the category archive lists every review in date order. The closest comparisons we have published are Insta360 X4: Battery Draining Faster Than It Should and Insta360 X4: Bluetooth Keeps Disconnecting.
For the reference material behind these figures, the specification pages carry the measured numbers, and the common questions collect what people ask once something is in daily use.
