Most RX-100 owners who try this same experiment at home will likely
never notice this horrid distortion, because Sony also did something
very clever to keep you from seeing it: they re-defined their RAW file
format to include lens correction attributes in the EXIF information.
...
They’re there so that high-end RAW processing software like Bibble,
DxO, or Lightroom could take note of those settings when opening the
RAW file, and automatically adjust the sliders to make it look like
what the camera would have produced had it been shooting a .jpg.
...
So what Sony did was extend that concept, making note of all the
optical corrections the .jpg engine would have made and write them to
the RAW file.

After loading the night-shot sample from
http://www.dkamera.de/testbericht/sony-cyber-shot-dsc-rx100/beispielaufnahmen.html
 :
http://www.dkamera.de/media/testberichte/sony/cyber-shot-dsc-rx100/6_beispielaufnahmen/bilder/4_real_raw/03.ARW?download

I see that the raw-file is a lot more distorted than the jpg-sample.

Do I need a plugin? Can Darktable use the processing info in the
raw-file?
