Sony Cinema Line · Official launch brief

The FX5 changes more than the specification sheet.

On July 22, 2026, Sony officially announced the FX5, a compact full-frame Cinema Line camera built around a newly developed stacked Exmor RS sensor and the BIONZ XR2 engine with integrated AI processing.

Its full-frame Open Gate capture and internal X-OCN workflow create new demands on optical resolution, aberration control, autofocus behaviour and lens metadata. That makes lens selection part of the production workflow—not an afterthought.

What is genuinely new?

Eight technologies that define the Sony FX5

The FX5 is more than a resolution update. Its biggest changes affect acquisition, exposure, monitoring, autofocus, audio and post-production.

01

5K full-frame Open Gate

The FX5 is the first Sony Cinema Line FX camera with full-frame 3:2 Open Gate. At launch, Open Gate is available in X-OCN, giving editors more vertical image area for 16:9, 9:16, square and anamorphic reframing.

02

Internal 16-bit X-OCN

X-OCN LT, C1 and C2 can be recorded inside the camera, providing a scene-linear RAW workflow without an external recorder. This is a major upgrade for compact rigs and high-end post-production.

03

Dual Gain Shooting

Dual Gain Shooting debuts in the Cinema Line FX series. It is designed to maximise latitude and reduce shadow noise, complementing the three Base ISO settings.

04

BIONZ XR2 with integrated AI

The new engine combines image processing and AI functions. It supports advanced subject recognition and deep-learning-based Auto Tracing White Balance for more stable colour under difficult lighting.

05

AI subject recognition AF

Fast Hybrid AF uses up to 759 phase-detection points, with human, animal and bird recognition, Real-time Eye AF and Real-time Tracking for moving subjects and shallow depth of field.

06

Anamorphic monitoring

Built-in de-squeeze settings include 1.3×, 1.5×, 1.6×, 1.8× and 2.0×, helping crews monitor anamorphic images correctly on set.

07

Production monitoring tools

Waveform Monitor, Histogram, False Color and Focus Map support exposure and focus decisions, while the CineAlta-inspired BIG6 screen keeps six critical settings visible together.

08

32-bit float audio and connected production

The XLR-H2 handle supports up to 96kHz/32-bit float four-channel audio. Wired LAN, 2.4/5/6GHz Wi-Fi and dual USB-C connections support remote control, transfer, timecode and power.

Available at launch

5K 60p · 4K 120p · Full HD 240p

Sony's launch announcement confirms these maximum frame rates. Full-frame 3:2 Open Gate is available with X-OCN recording.

Planned firmware update

5K 120p · cropped 4K 240p

Sony states that 5K 3:2 X-OCN 120p and 4K 240p require a future firmware update. Additional planned support includes XAVC S-I 3:2 full-sensor recording, a vertical interface and Frame Grab.

Open Gate and image scan modes

One sensor. Seven different capture windows.

The FX5 does not treat every recording mode as the same crop. Sony provides full-frame, full-frame crop and Super 35 scan windows so crews can trade field of view, resolution and frame rate for the needs of each shot.

Sensor coverageFull-frame · full height
Best useMulti-format master capture

Open Gate reads the full 3:2 sensor area, preserving extra image above and below a conventional widescreen frame. That gives editors more freedom for 16:9, vertical, square and anamorphic deliverables.

Lens implication: This mode asks for a full-frame image circle. Viltrox full-frame LAB, Pro and EVO lenses are the relevant starting point; APS-C lenses are not intended to cover Open Gate.
Open Gate protects reframing freedom

The full 3:2 readout is the most flexible choice when one shoot must feed landscape, vertical and cinematic deliverables.

Crop modes change the lens conversation

A smaller scan window narrows the effective angle of view. The same prime becomes visually tighter without changing the physical lens.

Super 35 creates a second lens route

The S35 scan window makes APS-C coverage relevant for supported workflows, but it should never be presented as full-frame or Open Gate coverage.

Launch versus future update

At launch, Sony confirms recording up to 5K 60p, 4K 120p and Full HD 240p. The headline 5K 3:2 X-OCN 120p and full-frame-crop 4K 240p modes require a future firmware update. Sony also plans XAVC S-I 3:2 Open Gate support through version 2.0 in or after August 2027. With Dual Gain Shooting, Sony states support up to 30p in FF 5K 3:2 and up to 60p in FF 5K 16:9 or 17:9.

Read the footnotes

The headline is 5K 120p. The useful story is in the limits.

Sony's mode chart is a strong visual hook, but the footnotes make the article genuinely useful. They explain what is available now, where Dual Gain changes the operating envelope, and why X-OCN places more responsibility on the lens and post-production workflow.

01

Launch frame rates are lower than the roadmap headline

The launch specification is up to 5K 60p, 4K 120p and Full HD 240p. Sony plans 5K 3:2 X-OCN 120p and full-frame-crop 4K 240p for software version 2.00 in or after August 2027.

Future update
02

Dual Gain Shooting has its own recording limits

With Dual Gain enabled, Sony lists up to 30p in FF 5K 3:2 and up to 60p in FF 5K 16:9 or 17:9. Base ISO is fixed at 800, and the mode is unavailable in FF crop 4.5K, FF crop 3.8K and Full HD.

Available now
03

Internal X-OCN changes the lens-correction conversation

Sony states that in-camera lens distortion correction is not applied to internally recorded X-OCN clips. Compatible Catalyst workflows may use embedded lens metadata later, so optical distortion, edge quality and verified metadata behaviour become more important when recommending lenses.

Lens workflow
Full-frame scan modes Use full-frame LAB, Pro or EVO coverage

FF 5K 3:2, 16:9 and 17:9 require a full-frame image circle. Open Gate also makes corner performance and distortion more visible.

Super 35 scan mode APS-C Pro becomes a supported crop-route candidate

AF 27mm, 56mm and 75mm F1.2 Pro can be discussed only for supported Super 35 workflows—not as full-frame or Open Gate lenses. Final FX5 compatibility still requires testing.

Why we recommend by series

RAW gives you more freedom. It also asks more from the lens.

Internal X-OCN gives FX5 users more grading latitude and a richer post-production pipeline. But a RAW-first workflow also puts more responsibility on the optical system instead of relying on a baked-in look.

Resolution, chromatic aberration control, distortion behaviour, autofocus and focus breathing all become part of the final image.

That is why the right recommendation is not one universal lens kit. It is a choice between four Viltrox product lines, each built for a different balance of image quality, speed, size and production style.

Viltrox has not yet completed production-camera compatibility testing with the Sony FX5. The following recommendations are based on mount, optical positioning and intended workflow. Final autofocus, correction, metadata and stabilisation behaviour must be verified on a production FX5 body.

01 / Flagship image quality

LAB

Peak resolution for demanding RAW workflows

For productions that want the highest optical standard, LAB prioritises fine detail, aberration control, low-light performance and professional physical operation.

02 / Professional all-round performance

Pro

High resolution with more everyday versatility

For creators who need professional sharpness, fast apertures and responsive autofocus across interviews, portraits, dialogue and commercial production, Pro offers a strong balance of performance and flexibility.

03 / Performance and size in balance

EVO

APO colour control for mobile production

EVO is designed for creators who want a refined balance of optical performance, practical size and everyday handling. Its APO approach helps keep colour fringing under control while supporting fast-moving documentary and hybrid workflows.

04 / Special crop-mode option

APS-C
Pro

F1.2 flagship optics for crop workflows

For creators intentionally working with a supported APS-C or Super 35 crop workflow, the Pro trio extends Viltrox's flagship APS-C optical design across a useful set of equivalent focal lengths.

Choose by production priority

Start with the image you need, not the longest lens list.

The same FX5 body can serve very different crews. Choose the product line that matches the job, then refine focal length around the shot list.

Maximum image quality

Commercial, narrative and premium portrait work

Prioritise edge-to-edge detail, aberration control and large-aperture rendering.

Start with LAB
Professional all-round use

Interviews, dialogue, beauty and client production

Balance strong optical performance with practical standard and portrait focal lengths.

Start with Pro
Mobile full-frame workflow

Documentary, travel, street and gimbal operation

Keep the setup more manageable while maintaining full-frame coverage and APO colour control.

Start with EVO
Crop-mode F1.2 option

Super 35 style framing and very shallow depth of field

Use only when the selected recording mode supports an APS-C crop and compatibility is verified.

Consider APS-C Pro

Compatibility comes before recommendation

Six things to test on a production FX5 body

A native E-mount fit does not automatically confirm cinema-workflow compatibility. The complete camera and lens system should be tested in the modes a crew actually plans to use.

01

AF-C and subject tracking

Focus stability, transition behaviour and subject recognition across working distances.

02

Lens metadata

Correct focal length, aperture, lens ID and production metadata in every codec.

03

IBIS communication

Focal-length reporting, stabilisation behaviour and post-production metadata.

04

Correction behaviour

Distortion, shading and chromatic-aberration correction in camera and post.

05

Focus breathing

Framing consistency during focus transitions and compensation support where available.

06

High-frame-rate stability

Reliable communication during X-OCN, crop modes and extended high-frame-rate recording.
