This conversation has been merged. Please reference the main conversation: Lightroom: LR4.1 RC2 messing up Olympus RAW files
The existing work-around provided by Adobe is to convert the RAW files into DNG using a plug-in, but this is an unacceptable solution since it doubles disk space usage or requires the deletion of the original files. I refuse to delete my ORF-format files because they are very useful, since they can be brought back into the camera for further RAW development when testing certain camera settings, or brought into Olympus Viewer for alternate RAW development.
The argument given by Adobe for why Lightroom cannot restore the full resolution of RAW files is that they are afraid of customers' existing crops being lost if they do this. However I'd like to point out that if someone is wishing to uncrop their image, all you would have to do is store the original crop in some metadata field somewhere, then pull it back later. Have a menu option called "restore this RAW file's original resolution" and warn the user it will remove any existing crops. They say yes, then it goes back to the original resolution. Next if they want to restore the in-camera crop ratio, they can just set it with Lightroom, or possibly have a menu option to "restore the original crop stored in metadata". Boom.
The lack of this feature makes Lightroom basically unusable for customers like me, who bought it assuming that it would have a basic feature like this. I think this is a show-stopper issue and Adobe needs to stop ignoring its customers who have been asking for this for a long time.
