Re: filmscanners: Canon 4000 scanner VS Nikon LS4000



Hello Brian. The Nikon scanner is not out of focus.
Nikon LS 4000 are sharp in the middle of the  film area but un sharp out 
against the sides and corner . The example are from  the right side of a 
slide  film.

Next small jpg file are from our test motive . The test motive shows in the 
middle of the jpg file.  This is from the left corner.
I hope that every one can se the difference in resolution and sharpness.  
Look below the text.
Nikon have a big problem with the depth of field. Best results gets with 
glass framed film and  100% film flatness. Low light source and to open 
f-stop lens construction is the main problem. Im a owner of 2 Nikon scanner 
LS2000 and LS 4000, they have the same problem.
Best regards
Mikael Risedal
