Hi, I have a chance to buy this scanner. Apparently, it's in very good
condition, but I want to find out more before I make a decision. Are there
any specific problems with this model,
The Nikon LS-8000ED is a very good scanner for all film formats, from
sub-miniature up to 6x9cm. It is, a firewire interfaced unit with
4000ppi resolution, 14-bit ADC and ICE3 hardware/software dust detection
and removal. It is essentially a large format version of the popular
LS-4000 scanner with two main differences:
1. It accepts a much wider range of film adapters for the various film
formats, but not the motorised film strip feeders. The scanner comes
with 3 adapters:
FH-835S 35mm unmounted strip holder for 2 strips of 6 frames (12 frames
in total).
FH-835M 35mm mounted slide holder for 6 mounted frames
FH-869S unmounted 120/220 film for 4 6x4.5cm frames, 3 6x6cm frames or 2
6x9cm frames.
2. Because of the much larger frame coverage, the scan times are
obviously slower. Nikon attempted to overcome this by introducing a new
3-line CCD which allowed a high speed scan by capturing 3 scan lines at
a time. However, in some/all of the LS-8000 units the mechanics simply
were not rigid enough to permit vibration to completely settle with the
larger steps between scan lines and consequently the high speed scan
mode resulted in a very unique type of banding structure parallel to the
CCD axis. When the high speed scan option is disabled, this problem
disappears.
As far as I am aware, this is the only major defect on the LS-8000.
and how does it stack up against the
others in it's class - particularly the Minolta? Many thanks.
I assume you are referring to the Minolta Scan Multi-Pro.
Similar film options and holders but with 16-bit ADC. Minolta are a
little deceptive on their specifications for their multiformat range,
with a bit of a smoke and mirrors coming into play. The resolution has
always been better on the 35mm frame sizes than on large format, so
guess which resolution takes the headlines? In the SMP this is a little
better than it has been in previous models and the difference is less
significant, bit significant nonetheless. For 35mm the Minolta SMP
scans a true 4800ppi scan, but for anything larger the scan is actually
4800x3200ppi and interpolated up to 4800ppi. Since interpolation always
results in loss of information, you will find the fixed 4000ppi of the
Nikon is almost always superior.
The other main difference is that the LS-8000, in common with other
Nikon scanners, uses a 4 colour (RGBI) LED illumination system with an
unfiltered single line (ignoring the high speed option) CCD. The
Minolta uses the more common fluorescent lamp illumination with an RGB
filtered 3-line CCD. Lamps are brighter than LEDs, so the scanner can
operate with a larger f/# lens, yielding greater depth of field, which
can be useful when scanning badly curled film. LEDs, however, are much
more reliable than fluorescent lamps, their colour purity is higher and
does not degrade with age. There have been reports of problems
obtaining replacement fluorescent lamps for some Minolta scanners
although I couldn't say if this was one of those reported.
