It has a couple of interesting points that were new to me:
- CMOS-family sensors often produce better quality images?

There is a good article in May American Cinematographer:
Quote
"Zarnowski expands, “The initial
promise of CMOS imagers was
hindered by the fact that they were
noisy [compared] to CCDs. This was
due to both Fixed Pattern Noise and
Temporal Noise, and as a result CMOS
imagers had objectionable patterns
that could be seen by the viewer and
didn’t quite have the same sensitivity
as CCDs. With the recent architecture
changes made to eliminate
FPN and the creation of overall lowernoise
pixels — through the addition of
pinned photodiodes — CMOS imagers
are now living up to their potential.”
“CCD technology was the superior
technology in the ’80s and probably
through the ’90s, but CMOS was on a
real growth curve because it’s a technology
that is used in all of the other semiconductor
manufacturing operations,”
agrees Glenn Kennel, president and
CEO of Arri, Inc. “Unfortunately, all of
the Moore’s Law’s improvements no
longer apply to CCD because there just
aren’t enough products being developed
for them. CCD is still a viable technology,
but it’s more expensive to make,
and it isn’t improving at the same rate.
In fact, it has reached a kind of plateau.
CMOS imagers continue to improve
and have now passed CCDs in sensitivity,
dynamic range and frame-rate capabilities.”
