There is a thread somewhere that *claims* compressed in fact give better dynamic range? I'm not sure how that can be, without going through the reasoning carefully. I personally just use uncompressed, unless my card is getting full and I don't have a spare one.... - LR can either leave the files as is in Leica DNG or convert to Adobe DNG. It does kind of defeat the claim of "Digital Negative" when Leica DNG may not be fully the same as Adobe DNG? Personally, I don't buy the Adobe DNG is superior to other RAW argument so I just leave it as Leica DNG. It's much faster anyway. When I am importing other RAW format (e.g. E-3 Olympus ORF), I do now convert it to DNG.
