I have been using Adobe DNG Converter for a very long time, currently the version 11.0.0.61, because I love the .DNG format and not having to deal with .XMP files for every single edited RAW file. I have converted Panasonic RAW files and, now Olympus .ORF files for years now without much issues.
Until a few days ago when I noticed some very strange artefacting in the .DNG RAW files. At first I couldn't explain it but I started wondering if it was some demosaic issue. It seems to affect green colour the most (from the few pictures where I noticed the problem) and in some cases it seems extremely noticeable, where the background green colour replaces the texture in the foreground. I exported these JPEGs with nothing but the default settings in Lightroom:
I noticed it first when editing a few images from burst sequence (mechanical shutter) where the green was bleeding into the subject (the green colour cast under the wings as well as the eye is very green tinted, wherein another image the underside of the wing was blue even though it was oriented opposite of the blue sky background).
I noticed this one this morning when I got home from work (made this picture 4 hours ago) and after converting the .ORF file to .DNG and importing it into Lightroom I noticed the right side bunny has green holes in the tip of the ears ... well, that's not right ... so I went to the original .ORF file (luckily I haven't formatted the card yet) and this (is a screenshot) how the .ORF file looks like:
No holes in the ears (don't know why the exported JPEG looks so much more contrasty, I have not made any changes to the image).
I can't find an explanation, for now, I think I will stop converting to .DNG until I find an answer.
