Re: Sprintscan120/Silverfast6 (& Glass holder) scan sharpness problem

2003-05-02 by Shilesh Jani

Yes it is.  Have you confirmed this with people at Silverfast? I know 
SF 6 cannot manually focus the SS120.  But there is a tab for this 
function - must be in all versions of SF.  It toggles between being 
grayed out and showing an "A".  I have assumed that "A" stands for 
autofocus - hey how about the SF documentation, eh ;-(.  

Quite frankly, I have not encountered "soft" scans when scanning 
transparencies (which is mostly what I use).  But, I am going to 
explore this further.  For me, at least, it may be a lesser problem 
because I don't scan too many negatives, and in fact have recently 
decided NEVER to shoot them any more.  I like the grain I get from 
Fujichrome Provia 400 when pushed 1 or 2 stops.  And, it is so much 
easier to scan than Tri-X or Ilford Delta 3200.  I like some features 
of SF 6, but I can live without them.

Is it possible that the problem is in your scanner?  If you like, I 
would gladly scan a couple of your negatives  to test it out.  
Contact me off-list.

If all esle fails, time to be rid of the scanner, and go with a 
Minolta or Nikon (argh  $$$$).

Regards.
