Both Adobe Raw and Capture One 21 now support raw files from the new Sony a1.
For the support of the Sony a1 raw files the following minimum versions are required:
Lightroom CC: v4.2 or higher
Lightroom Classic: v10.2 or higher
Adobe Camera Raw: v13.2 or higher
Note: At time of writing these versions of Lightroom are not yet showing up as available to download. Hopefully they will be available before the day is out.
You can find Adobe’s full list of supported cameras here.
One new feature worth mentioning in Camera Raw 13.2 is Super Resolution, this doubles the linear resolution of a photo. See this blog post from Adobe for further details.
