Re: filmscanners: LS4000 and sharpness

["Tom Scales" <tscales@attglobal.net>]

All points well taken.  My whole point of switching from the Polaroid to the
Nikon, though, was the I wanted the roll film carrier. Now, what I am
reading seems to imply that I have to manually adjust the focus on each
individual frame.  Perhaps I am misreading that, and a generic focus at a
middle spot would work, but why didn't Nikon do their software right then?

I want to be able to load a roll of film, go to bed, and wake up to 36
properly exposed, properly focused scans.  Why else have the roll film
adapter?

I might as well keep doing them 6 at a time.

Bottom line, it feels like a scanner that is late to the market and was
rushed.  Given time and releases of the software, it might be an incredible
scanner, but for now, I'll wait.

P.S. David, hint hint, give me the roll film adapter and I won't defect.
