Sony RX100 RAW files lens correction
Opening Sony RX100 RAW files in darktable results in distorted images - the internal lens correction is not applied. Photoshop/Lightroom open these RAW files without any issues. The camera uses builtin lens correction algorithm and probably stores the values in RAW files themselves. JPG files look just fine. There is RAW file in the attachement and JPG file as well. I own the camera so I can provide any information/RAW examples needed.

Unfortunately, Darktable cannot interpret the correction data in the RAW yet. This is certainly a nice addition, but it may make extensions in Lensfun necessary, too.
Anyway, Lensfun contains correction data for this camera in its upcoming version. You may download http://lensfun.berlios.de/db/version_0.tar.bz2 and replace the content of /usr/share/lensfun with the content of that bzip2 file. It does not correct TCA or vignetting, however. See http://wilson.bronger.org/calibration for how to do that.
