Re: filmscanners: LS4000, LS2000 and sharpness

This is exactly what I have discovered I need to do with my LS2000 - set 
the focus point closer to the edge of the film.  The small depth of field 
on the LS2000 is the greatest problem I have found with this scanner, and 
the main reason I will be nervous of the LS4000.
