Well that's part of the story but is not necessarily significant. The BIG
difference is how much information the camera throws away at the outset. You
can't get that back. If you want to extract the most information from the
M8, DNG is the only choice. That may not be important for some purposes
certainly.
But remember that Craig's original question was asking about advantages and
disadvantages of shooting DNG vs. jpg.
Craig has explained that his pro friends use jpg and it suits their purposes
fine. No reason to doubt that. It doesn't invalidate the technical
differences though.It just says that those aren't a priority for the way
they work.
Having said that I don't think that the M8 implements jpg especially well
compared to the mainstream cameras (which those pros are undoubtedly using).
