Happy to move this to another post, instead of cluttering this one. But that's not all that stored in DNG files. It keeps additional information. If you want to play devil's advocate I'm sure it can't decode 100% of all raw file data, but in cases like this the processing difference is what shows up. There was a previous thread with similar issues that were based on default settings in processing from Adobe products with noise reduction that the olympus processing didn't do by default. (in the specific case it caused a bunny to have different colored ears)Is that all there is and ever will be in a RAW? Some manufacturer specific data may get dropped in the process.
