Compressed DNG or Uncompressed DNG ?
DNG stands for Digital Negative.
As with the Leica M9 I recommend shooting Compressed DNG as this is lossless*. This basically means that when you shoot an image, the image contain a lot of 'empty' information, and compressing the DNG image simply is not storing the empty fields of information. This is how the size of the file is reduced to half.
The discussion of lossless is ongoing. Will future technology be able to make information out of 'empty' fields? I don't believe there is any information in the empty fields, so I decided to shoot lossless. And if there were information in the 'empty' fields, my policy is to finalize photos today to final editions, not to re-open old photograph to re-edit them later.
If you are unsure, shoot Uncompressed. It will take twice the space and make the camera writing to the card slightly slower as well as working in Lightroom slightly slower. But it is not the end of the world.
