Sony FX6 Firmware 6.00 Brings Blackmagic RAW, BIG6 Interface, and AF Upgrades

Firmware version 6.00 for the Sony FX6, released March 19, 2026 as a free download, delivers what analysts called one of the most substantial feature additions the compact Cinema Line camera has received since its 2020 launch. The headline additions are the BIG6 home screen inherited from Sony's CineAlta lineup, external Blackmagic RAW recording via HDMI, and a broad set of workflow, connectivity, and image quality improvements that also include AF upgrades and HLG Mild support in custom shooting mode.

The most visible change is the BIG6 interface, which consolidates six essential shooting parameters into a single view: frame rate, ISO, shutter, iris or ND filter, Look, and white balance. Previously standard on the VENICE and BURANO, its arrival on the FX6 is a meaningful ergonomic upgrade for anyone operating across multiple Sony Cinema Line bodies on the same production. As a Sony representative described the feature at BSC Expo 2026 in London earlier this year: "We call it the big six where you have a very simple overview of what the camera settings are and introducing a way to quickly change them."

Sony also updated the shooting screen layout with black borders, a detail noted in the company's Cinema Line firmware roadmap.

The addition of Blackmagic RAW recording via HDMI video output is the other major headline. FX6 shooters can now capture BRAW externally over HDMI, opening a more flexible raw acquisition path for productions already working within a Blackmagic Design ecosystem. Sony's documentation does not specify which external recorders are officially supported beyond noting HDMI as the connection standard, so confirming compatibility with specific Blackmagic devices before a shoot is worth doing.

The update also brings HLG Mild in custom shooting mode, AF improvements, and broader workflow and image quality refinements, though Sony has not yet detailed the specifics of the autofocus changes in publicly available release documentation.

V6.00 follows what CineD described as Sony's "familiar pattern of trickling down features from higher-end CineAlta bodies," a strategy the company has applied across previous FX6 firmware releases. The FX6 has been a mainstay in documentary and narrative production since launch, and Sony demonstrated the upcoming update at its booth at BSC Expo 2026 before releasing the production build on March 19.

The FX6 update arrives alongside a broader 2026 Cinema Line firmware wave. The FR7 received its own v4.0 update, which adds support for OpenTrackIO, described as the new standard for virtual production camera tracking designed by the SMPTE RIS OSVP group. The BURANO and VENICE 2 also received updates, with VENICE 2 firmware v4.1 noted to not support Angle/Auto Shutter. Even the A7S III, outside the Cinema Line family, received a version 5 update as part of the same rollout cycle.

All updates are available as free downloads from Sony.
