jono slack over at the "getdpi" forum has some downloadable dng files from an M9M that you can download and process with your favorite software for comparison sakes. I don't know how much longer the downloads will be available but there are six or seven of them sattered on the forum thread page. You can also post your processes jpgs on the site as others have done. here is the link: http://forum.getdpi.com/forum/leica-m-x-r/
