RAW digital photography formats are typically not converted between each other, and there is probably no program that could do it anyway, which makes mrw to raf conversion unlikely. RAWs are generally either exported to a digital negative (DGN) or to JPEG/TIFF format.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
