as an intermediate format in your workflow yes, by all means... it is not different from tiff or whatever... as an original in camera raw format - dream on... market share of DNG using companies is going down... Samsung dropped DNG, Ricoh purchased Pentax and both are dropping off radar behind with a surge or mirrorless cameras from the likes of olympus, panasonic, sony, fuji...
That has precisely nothing to do with their adoption of DNG as their RAW format.
I am sorry but there is so much BS already out there.
As for your apparent criticism of Jeff - what camera exactly would you like him to use?
DNG would make a perfectly acceptable archival format.
It would make a perfectly acceptable RAW format.
However the industry could adopt another format as standard.
However most of the big camera manufacturers just refuse to acknowledge the chaos that the continual spawning of proprietary RAW formats has already caused and will continue to cause.
IMO the real argument is not about supporting or denigrating any particular company but rather about a sustainable open format RAW format verified by the ISO.
This will allow now orphaned RAW formats to be be converted to something usable before the ability to access them is lost. (Technically they are accessible but in practise for most people they are orphaned because the software required needs obselete hardware and OS's.)
It will also allow RAW images to be accessible right out of the camera by any software - third-party or otherwise - that is currently not the case.
Nuff said.
