Blackmagic PYXIS 6K Beta Firmware Brings Phase-Detection Autofocus Support

Blackmagic Design posted Camera firmware 10.0.3 RC1, a forum-distributed beta, to the Blackmagic Design forums last Thursday, delivering phase-detection autofocus support to the PYXIS 6K alongside a set of accompanying autofocus refinements. The build also covers the Cinema Camera 6K, marking a clear step beyond the limited pre-beta PDAF work Blackmagic had been quietly developing.

Kristian Lam, the PYXIS product manager, shared the beta directly on the Blackmagic forums. Interested testers sign up via a Forms document, entering their email to receive the download through ShareFile. Blackmagic is also asking testers to submit lens compatibility reports via a dedicated Google Form linked in the forum thread, signaling that real-world lens pairing data is a core goal of this RC phase.

PDAF is the headline change. Where contrast-detection systems work by hunting through the focus range until sharpness peaks, phase detection calculates subject distance directly from sensor data, producing faster acquisition and more stable tracking with less of the hunting behavior that has frustrated PYXIS 6K users on gimbal-heavy or run-and-gun shoots. Beyond PDAF, the build adds the ability to resize the focus box in continuous autofocus and object tracking modes, refines face detection so the camera automatically locks onto a detected face once a region is tapped, and introduces linear focus support for compatible L-Mount lenses. Early testers reported that linear mode allows follow-focus end-stops to be used with consistent results regardless of racking speed, a meaningful gain for operators running external follow-focus systems.

A few wrinkles are worth noting. Linear focus is currently an L-Mount-exclusive feature; at least one PYXIS 6K EF mount user found the relevant menu option greyed out. Blackmagic confirmed this is expected behavior and said a future release will update the UI to default that setting to Off on EF cameras. EF mount owners are technically supported by the build, but Blackmagic acknowledged that testing on the EF variant has been limited. The company is encouraging those users to experiment with the Transition Speed settings found on page 11 of the camera's Settings menu, as EF lenses appear more sensitive in this build. Full functionality, including linear focus, also requires lenses to be updated to their latest firmware versions so they can communicate properly with the camera's new processing algorithms.

The build fixes at least one pre-existing bug: a startup hang that occurred when a headphones jack was connected to the camera.

Community reaction within the early tester pool has been positive. One user who had been running previous PDAF builds on the Cinema Camera 6K described Blackmagic's implementation as faster and less complicated to operate than Lumix's equivalent. The PYXIS 6K has been a consistent seller for Blackmagic since its introduction at NAB 2024, and autofocus has been one of the most-requested capability expansions for the platform.

Blackmagic is advising testers to use the firmware in non-critical environments while the autofocus system is refined, and the Google Form in the forum thread remains open for ongoing lens compatibility reports.
