Re: filmscanners: LS4000 and sharpness



Well, that pretty much proves that the problem is depth of field, which 
is what you and others suggested.  It also implies Nikon could have 
played with the software to calibrate the focusing feature to accomplish 
this very easily, even without a hardware change, just by using an 
average offset from the middle (and called it "curved film focusing" as 
a second option, rather than having to go in and defeat the autofocus 
and do it manually.

I recommend you write Nikon and inform them of this, and being one of 
those righteous companies, whose advertising claims can be taken fully 
at face value, I'm sure they will have a software fix for you within 
days, if not sooner.  ;-)
