Canon Inc. has released Digital Photo Professional version 3.11.26 for download
. Unfortunately for many of us, it is the Japanese version. Navigate the menu to get to the proper download page - then look for the red arrow button to download the update.
This update should correct the soft conversion problem with Canon EOS 5D Mark III
RAW images and hopefully corrects the same problem with Canon PowerShot G1 X
I expect the English version to show up very soon.
