The recent tests I did with the LS30 didn't show 4 pass results to be
significantly fuzzier results IMO. But I didn't seem to gain much
information from the extra passes so I haven't persisted with them. AFAIK
the quality of alignment of multipasses depends a lot on the way the CCD and
film interact - whether the film moves, or the CCD moves, and how accurate
the mechanism is. One VERY important thing - focus on the preview not the
main scan, or each pass will have a different focus setting and the end
result will be hopelessly fuzzy. This says a lot about the accuracy of the
autofocus system IMO. :)
