Sony FX5 Data Calculator
The Sony FX5 is the first FX-series body with internal 16-bit X-OCN RAW — the VENICE and BURANO codec, now in a handheld Cinema Line camera. 5K Open Gate 3:2 up to 60p, three base ISOs, and a newly developed full-frame stacked sensor. This page covers the recording media math.
Sony FX5 X-OCN Data Rates
X-OCN rates derived from Sony's recording-time tables; XAVC rates are Sony's published Mbps. X-OCN comes in three tiers on the FX5 — LT (the established VENICE/BURANO tier) plus new C1 and C2 tiers that compress harder for smaller files.
| Format | Resolution | Frame rate | Data rate |
|---|---|---|---|
| X-OCN LT | 5K Open Gate 3:2 (4992×3328) | 24p | 712 Mbps |
| X-OCN C1 | 5K Open Gate 3:2 (4992×3328) | 24p | 536 Mbps |
| X-OCN C2 | 5K Open Gate 3:2 (4992×3328) | 24p | 429 Mbps |
Sony FX5 Storage — Quick Examples
| Shoot | Data rate | Per minute | Per hour |
|---|---|---|---|
| 5K Open Gate X-OCN LT 24p | 712 Mbps | ~5.3 GB | ~320 GB |
| 5K Open Gate X-OCN C1 24p | 536 Mbps | ~4.0 GB | ~241 GB |
| 5K Open Gate X-OCN C2 24p | 429 Mbps | ~3.2 GB | ~193 GB |
A 1 TB CFexpress Type A card holds roughly 3 hours 7 minutes of 5K Open Gate X-OCN LT at 24p — or about 5 hours 10 minutes in C2. For RAW workflows this is remarkably storage-light: the R6 V's 7K Open Gate RAW consumes 1.17 TB per hour; the FX5's 5K X-OCN LT is under a third of that.
Recording Media for the Sony FX5
Dual slots accept CFexpress Type A or SD UHS-II. Internal X-OCN requires CFexpress Type A with VPG400 certification. SD UHS-II handles the XAVC compressed modes.
- Lexar Professional GOLD 1 TB CFexpress Type A — the only 1 TB Type A shipping. CFexpress 4.0, IP68. Three hours of X-OCN LT per card.
- Angelbird AV PRO CFexpress A v4 1 TB — CFexpress 4.0 with free lifetime data recovery. Pro-tier alternative at the same capacity.
- Sony Tough 640 GB CFexpress Type A — Sony's own VPG-certified card; the safe pairing for a Sony cine body. ~2 hours of X-OCN LT.
- ProGrade Digital Iridium 480 GB Type A — CFexpress 4.0, VPG-800 sustained writes.
Key Features for Storage Planning
Internal X-OCN RAW — first FX body with it. 16-bit sensor data at data rates a third of comparable RAW formats. The C1/C2 tiers make RAW affordable on storage: C2 at 5K 24p uses less space per hour than many 4K All-Intra XAVC modes.
5K Open Gate 3:2 — full sensor capture for reframing vertical and horizontal deliverables from one master file. Up to 60p at launch. 5K 120p arrives with firmware V2.0 (August 2027 or later).
Three base ISOs (800 / 4000 / 12800) — a first for Sony. No storage impact, but it changes how much usable footage survives low-light shoots — plan capacity for more keepers.
Firmware 2.0 roadmap — 4K 240p X-OCN and Open Gate XAVC-I are announced for a future update. Data rates for those modes aren't published yet; we'll add them when Sony does.
Frequently Asked Questions
What recording media does the Sony FX5 use?
Dual CFexpress Type A / SD UHS-II slots. CFexpress Type A (VPG400) is required for internal X-OCN RAW. SD UHS-II covers XAVC modes.
How much storage does the FX5 need per hour of X-OCN?
At 5K Open Gate 24p: LT (712 Mbps) ≈ 320 GB/hr, C1 (536 Mbps) ≈ 241 GB/hr, C2 (429 Mbps) ≈ 193 GB/hr. A 1 TB CFexpress Type A holds ~3 hours of LT.
What is X-OCN and how is it different from XAVC?
X-OCN is Sony's 16-bit compressed RAW from the VENICE/BURANO line — maximum grading latitude at manageable data rates. The FX5 is the first FX body to record it internally. XAVC is Sony's conventional 10-bit codec family at lower rates; the FX5 records both.
Does the FX5 record Open Gate?
Yes — 5K 3:2 (4992×3328) up to 60p in X-OCN. 5K 120p in 16:9. 4K 240p X-OCN arrives via firmware 2.0.
When does the FX5 ship?
Orders opened July 28, 2026. Shipping has slipped from August to September to October, and is now expected early-to-mid November 2026 — Sony Germany and France list 16 November. No globally confirmed date. Sony's Help Guide is now live and its XAVC bitrates are reflected here. X-OCN remains recording-times-only in Sony's documentation.
