Blackmagic’s Cinema Camera 6K gets continuous AF, making it a more competitive budget cinema option

Blackmagic has released a firmware update that adds continuous phase-detect autofocus, complete with object tracking and face detection, to its full-frame Cinema Camera 6K. This makes the camera more competitive in an increasingly crowded landscape of video-centric cameras focused on owner-operators and creators.

When the $3000 Blackmagic Cinema Camera 6K launched, it could acquire focus on something in the center of the frame, but it was a one-time operation; it wasn’t able to keep the subject in focus as it or the camera moved. While this wouldn’t have been a deal-breaker for many users – as the “cinema” name implies, much of its target audience will be using manual-focus lenses with focus pulling equipment – it also narrowed the scope of what you could do with it. It would work fine for more careful, scripted shoots, but wasn’t really ideal for more run-and-gun productions.

Now, though, the camera will be able to continuously focus on a human subject, tracking their face, or on a generic subject through object tracking. Blackmagic also isn’t making you completely give up control to use autofocus; the camera has settings to control how fast it transitions focus, and lets you pause autofocus by holding down a button. That way if your subject goes from moving to stationary, you can make sure the AF system isn’t going to pulse or try to focus on something else.

That last point, however, highlights a potential gap between the Cinema Camera 6K and other video-focused cameras, like the Sony FX3, Canon EOS R6 V and Nikon ZR. Those cameras use AF systems that are much more mature, so you don’t have to worry as much about managing them; you can just leave them on, and trust them to keep your subject in focus in most situations. While Blackmagic’s autofocus system has been out in public beta for around a year now, early adopters reported mixed results, and it’s still not as tried and tested as the others.

However, this full release is a starting point for the company’s autofocus ambitions and at least puts the Cinema Camera 6K in the conversation with those other cameras, giving people who need autofocus another option that has a robust set of features. It offers 6K open gate recording and internal Raw, full-size HDMI and mini-XLR connectors, a 5″ rear display and an optional detachable EVF. It also uses L-mount for lenses, which is relatively adaptable and has a growing selection of native options.

Hopefully now that the Cinema Camera 6K’s autofocus support has fully launched, we’ll see it come to more cameras in Blackmagic’s lineup. While not all of them will have the phase detection hardware on their sensors, the company promised it’d be coming for more, unspecified cameras when it initially announced the feature last year, and it’s currently available in beta for the Pyxis 6K.

The Blackmagic Camera 10.2.2 firmware that enables autofocus is available as a free download from the company’s website. It also adds support for Blackmagic’s cloud streaming system, 4-channel audio recording and up to 10 minutes of pre-recording, letting you save the moments before you press the record button.
