I just went back to the Popular Photography issue that
reviewed the new scanners, and what I saw was very different from what
was said here earlier today. They rated the LS-4000 Very highly. In fact,
maybe too highly...
Test Results: Resolution: extremely high (60 lp/mm); Color Accuracy:
Excellent; Shadow Detail:
high, ... Image Quality Rating: Extremely high, etc.
It delivered "the highest test results in this roundup along with
the Polaroid SprintScan 120". The "true 42-bit
color" sounds like they bought some puffery, but overall, these are
their conclusions based on their in-house tests.

Tomasz, you're right. At least in some regards.
CCD-based scanners are far from perfect, and even
the newest generation shows some (if not all) of the
inherent problems with the technology. As with
microprocessors, progress has been evolutionary, not
revolutionary. We have more pixels now, and we can
finally scan 120 film at the same resolutions that
we'd been using for 35 mm. Aside from that, the
changes are mostly cosmetic, IMHO.
If you want "perfect" scans you may have to go with
a drum scanner. The Imacon line of scanners are also
pretty nice (and mucho $$$). I think they're still
CCD-based, but they do something clever that the
Nikons, Polaroids and Minoltas don't.
It's no accident or surprise that the reference
scan on Tony's filmscanner-reviews site is done
with a Howtek scanner and fancy 3rd-party driver

But hey - maybe that banding I've been seeing on
dense negatives is a symptom of poor Dmax? I dunno.
At one point a couple of weeks back, I'd convinced
myself that the dynamic range of the LS-8000 was
markedly better than that of my Epson 1640SU,
which I'd been using to scan 645 negatives before
acquiring the LS-8000.
In the last week or so I've been scanning 35 mm
stuff on the LS-8000, and results are mixed. Some
scans are perfect, some show banding. Fixes
suggested by Nikon Tech Support help sometimes,
but not always. I'm wondering if the the high
temperatures here are a problem, also.
Fancy lenses and auto-focus (as in the Nikon 4000 and
8000) may also be a mixed blessing. In some regards,
I miss the simplicity of my existing and much
"simpler" 35 mm scanner. I worry about that 14-
element zoom lens in the LS-8000, and I have seen
mis-focusing on some slides.
