I think a lot of the difference in the look of digital versus analog is due
to the shorter focal length lenses used, to cover the relatively smaller
'film' plane. These lenses have different DOF for the same acceptance
angle, and have different diffraction characteristics as well, not to
mention whatever design idiosyncracies are imposed in matching the
characteristics of pixelated image planes and detector spectral sensitivity.
I think lens differences affect the relative characteristics of scanners as
well, although I haven't seen it considered in the amateur press, and I
don't read the professional optical press.

"Warner's Cookson is one of the industry's voices of caution in the digital
production debate. In a demonstration for other studio executives at the
Warner lot, he compares a scene shot using film against three versions shot
with high-end digital cameras. The film version is markedly better than all
three digital versions.
"Its resolution is better, and the way it handles light and shadows
superior. Some of this may simply be the result of viewer conditioning. The
movie-going eye is used to accepting the effects of film.
