Open gate, internal RAW, three base ISOs, all real, all shipping in August 2026. The 120p headline that sold the keynote lands in firmware v2.0, scheduled for August 2027. This is not a one-off.
On paper, the FX5 is the camera FX3 owners have been asking Sony for since 2021. A new 16.6MP stacked full-frame sensor, a BIONZ XR2 chip with a dedicated AI unit, three base ISOs at 800, 4000 and 12800, and, for the first time below the BURANO, open gate recording with internal 16-bit X-OCN RAW. No external recorder, no compromises, a genuine mini-VENICE for $4,999. Sony earned every headline it got out of the July 22 announcement.
Then you read the fine print. The 5K120 open gate mode that anchored half the coverage, the 4K240p crop, open gate in XAVC S-I, a vertical shooting UI and a frame-grab tool, none of it ships in the box. All five sit behind a version 2.0 firmware update that Sony has confirmed for August 2027, a full twelve months after the camera itself goes on sale. Buy the FX5 today and you are, by Sony’s own timeline, pre-ordering half the camera.
What You Actually Get On Day One
Strip out the deferred features and the launch spec is still strong. 5K open gate at up to 60p in X-OCN, 5K at 60fps in standard 16:9, dual gain with a claimed 15 stops of latitude, five-axis stabilization, and improved subject recognition across humans, animals, birds and vehicles. It genuinely answers most of what the FX3 got criticized for. The problem is Sony didn’t stop the keynote there.
| Feature | Status | Availability |
| 5K60 Open Gate, X-OCN RAW | Launch | August 2026 |
| Triple-Base ISO, Dual Gain (15 Stops) | Launch | August 2026 |
| 5K120 Open Gate, X-OCN RAW | Firmware 2.0 | August 2027 |
| Open Gate Recording in XAVC S-I | Firmware 2.0 | August 2027 |
| 4K240p (cropped full-frame) | Firmware 2.0 | August 2027 |
| Vertical-shooting optimized AI | Firmware 2.0 | August 2027 |
| Frame-grab from video clips | Firmware 2.0 | August 2027 |
Look at that list again. The FX5 is being sold, right now, at full price, against competitors like the Canon EOS C50 and the Panasonic S1II on the strength of a 120fps open gate mode that will not exist on the camera you receive. Sony gets to win the spec-sheet fight in every August 2026 review roundup while quietly pushing the actual delivery of that win into the next fiscal year.
Why This Feels So Familiar
Sony has a documented habit of announcing a camera’s ceiling and shipping its floor, then closing the gap with a firmware update long after the review units have gone back.
- November 2023
Sony used the a9 III launch event to announce that the a1 and a7S III, both already a couple of years old, would finally get FTP improvements, relay playback and other workflow features. Users had been asking for parity with Nikon and Canon’s more aggressive firmware cycles for years before Sony committed to a date. - March 2024
Those promised updates actually landed, more than forty combined changes across the a1, a7S III, a7 IV and, later, the a9 III. C2PA content authentication arrived with them, a feature Sony had joined the standards body for back in 2022, two years before it reached a camera. - Ongoing
Industry coverage of Sony’s firmware strategy has repeatedly used the word “outdated,” pointing out that Nikon and Canon tend to bake features in at launch rather than trickle them out on a separate calendar. Even Nikon’s Z9, cited as the counterexample, still held some functions back for post-launch firmware, so Sony isn’t alone in this. It’s just unusually consistent at it. - August 2026
The FX5 repeats the exact shape of the pattern, except this time the withheld features are the ones the launch marketing leaned on hardest.
The Annoying Part
Delayed firmware for workflow features like FTP or content authentication is one thing. Nobody buys a camera because of C2PA metadata. But 5K120 open gate and 4K240p are not workflow footnotes, they are the two specs that made the FX5 launch headline read like a paradigm shift instead of an incremental FX3 refresh. Sony needed those numbers on the announcement slide to justify sitting the FX5 between the FX3 and the FX6 at a price that undercuts neither. Whether the hardware could actually do it on day one seems to have mattered less than whether the press release could say it.
There’s also a quieter business logic here worth naming. Open gate lived exclusively on the VENICE 2 and BURANO until this camera. Handing the FX5 the full, unrestricted version of that capability on day one would have made it a much harder sell against Sony’s own flagship cinema line. Gating the fastest, most flexible version of open gate behind a year-long wait protects that hierarchy while still letting Sony claim the feature exists on a $4,999 body.
None of this makes the FX5 a bad camera. What it makes it is a familiar one. Sony keeps building genuinely excellent hardware and then treating the software that unlocks its own headline specs as a separate product to be released on its own schedule. If you can live on 60p open gate for a year, buy it. If you’re buying this camera for the 120p slow motion that got it on every homepage in July, you’re not buying a camera. You’re buying a very expensive pre-order.
