Blackmagic PYXIS 12K Phase Detect Autofocus – First Beta Build Now Available for Testing

Firmware Update

Blackmagic Design has released a beta build that brings phase detect autofocus to the PYXIS 12K for the first time. Until now, the feature was limited to the company’s Bayer-sensor cameras, and Blackmagic had never confirmed that the 12K RGBW sensor could support it at all. This test build settles that question. Here is what the beta includes, and what to know before installing it.

The new build is Blackmagic Camera 10.2.96, and it adds phase-detect autofocus (PDAF) to the PYXIS 12K with the same feature set and controls already shipping on the Blackmagic Cinema Camera 6K and the PYXIS 6K. According to Blackmagic, only the Mac installer is available for now, since the Windows installer is currently broken. The company is distributing the build for testing and gathering feedback through a dedicated thread on the Blackmagic forum.

A question that goes back to NAB 2025

The significance of this build goes beyond a routine firmware drop. When the PYXIS 12K was announced, we sat down with Blackmagic’s Craig Heffernan, and he told us that bringing capable phase-detect autofocus to the 12K model would require considerable engineering work, since the camera’s RGBW sensor is an entirely different technology from the Bayer sensor shared by the Cinema Camera 6K and PYXIS 6K. You can revisit that conversation in our NAB 2025 video interview.

Since then, there has been no official word on whether the 12K sensor even contains the phase detection pixels needed for the system, and PYXIS 12K owners have repeatedly asked Blackmagic for clarity on the forum. Meanwhile, the Bayer-sensor cameras moved ahead: PDAF first appeared on the PYXIS 6K as a test build back in March, then graduated to a stable public release with the Camera 10.2 update in June. The 12K sat on the sidelines throughout, which made the sensor question look increasingly open. This beta answers it: the RGBW sensor can do phase detection, and the rollout has now reached the top of the PYXIS line.

What the beta brings to the PYXIS 12K

Blackmagic states that the feature set and controls match what the Cinema Camera 6K and PYXIS 6K already offer. On those cameras, that means continuous phase-detect autofocus with face detection, object tracking, and a resizable focus box, rather than the single-shot contrast-based system Blackmagic cameras relied on for years. PDAF calculates subject distance directly from the sensor, so acquisition is faster, and tracking is more stable, with far less of the hunting behavior that made contrast detection impractical for moving subjects.

For a box-style camera like the PYXIS 12K, this matters more than it would on a traditionally operated cinema body. The form factor is a natural fit for gimbals, remote heads, crash cams, and multi-camera interview setups where nobody is standing behind the camera pulling focus. Reliable continuous autofocus turns those configurations from a compromise into a workable default, especially for solo operators running the camera through the Blackmagic Camera app. If you are weighing how the camera performs more broadly, our PYXIS 12K Lab Test measured 12.8 stops of dynamic range at SNR = 2 at ISO 800, alongside a rolling shutter of 24.1ms in full 12K that drops to around 11ms in 8K modes.

Mac only for now, and how to roll back

The distribution comes with two caveats. First, this is a test build, not a general release, so it belongs on cameras used for evaluation rather than on a paid job. Second, version 10.2.96 is currently available as a Mac installer only. Blackmagic says the Windows installer is broken at the moment, so Windows users will have to wait for a corrected package before they can join the testing.

Reverting is straightforward if the beta misbehaves. Blackmagic advises downloading the latest general release from its support site and running the updater on the camera, which returns the PYXIS 12K to the current stable firmware. Feedback on the autofocus behavior is being collected in the forum thread linked above, and given how the PYXIS 6K rollout went, real-world reports from testers will likely shape how quickly this feature reaches a stable public release.

PYXIS 12K owners, will you put the beta on your camera, or wait for the stable release? Don’t hesitate to let us know in the comments below!
