Atomos has just released a firmware update, which enables full-frame ProRes RAW recording to the Ninja V from the Sony a7s III. Furthermore, AtomOS 10.54 firmware is of course free, and enables 4K/60p ProRes raw recording from the a7s III

ProRes RAW in 4.2K Full Frame!

And what’s more interesting with the way Atomos record the signal, is that they read the full sensor, which is about 4.2K, giving you some extra resolution, which will downsample nicely to a 16:9 UHD frame size. See more on the 4.2K resolution in the details below.

Moreover, the Sony a7s III is scheduled to start shipping in most places within the next ten days, so this update will make lots of users happy. In addition, the Atomos Ninja V can also record ProRes or DNxHR in 4K *UHD up to 60p from the a7s III.

Check out the details and particulars below.
