I didn't look at the files but my guess is that it's not about some compatibility level (I wasn't even aware that was a thing, the DNG specs don't mention it) but just an unsupported feature in the DNG. Most likely deflate compression which rawspeed doesn't support (yet). > Thanks > Matthias Tobias
