for me the big stinker with Nikon is NOT being able to handle all my images in Lightroom (which i feel is a great programme) as it does NOT open up RAW files as well as it does in Capture NX2 IN MY OPINION....Hasselblad and Phocus is another example....the .fff files it generates have to be treated in Phocus before anything else = loads of time wasted
So, have Leica managed to output perfect images onto the DNG format unlike Hasselblad, Nikon and everyone else?? will be interesting to see......
The DNG format contains information regarding the color reproduction. ACR was criticized for the colors; photographers often expect the same colors, which they get from an in-camera JPEG. Leica may manage to pass "good" color reproduction specification along the raw data, i.e. such, which their customers like.
However, that is only one aspect of the image rendering. Even more: this aspect became a secondary issue with the DNG profiles. Adobe delivers a set of profiles for each camera, and users can develop their own profiles. There is room to improvement, but it is a very good start; the color rendition is much less of a problem now than it was for a year ago.
Other raw rendering issues can not be solved as of now. Example: noise reduction and CA elimination - ACR sucks, and Leica can not do anything in this regard short of pre-processing the raw data in-camera, and that would be foolish.
