Dynamic range is probably not the issue, as decent digital cameras can
capture a broad range of light values. However, the the contrast range --
the ability to render subtle shadings -- is visibly less than one can get
with film. I suspect that this is a difficult matter to discuss in an
objective way. Sharpness is easier to define and present objectively. It's
difficult to speak of color rendition in objective terms, and it may be
more related to contrast range (color depth) than dynamic range. As with
film, contrast range is a trade-off against sharpness, and it appears that
Leica has made the choice to emphasize this quality in the DMR. A broader
contrast range might explain why Peter finds it easier to acquire the
color of his floral shots with the DMR.

I suspect that "the market" prefers the higher sharpness with lesser
contrast range, and Puts' review only acknowledges that preference.
