Re: filmscanners: Nikon 4000ED Focus problem



After the Nikon Jaggies and now this, I will look elsewhere if/when I upgrade.

I might accept this sort of problem from a cheap SLR zoom lens, but what's
the point of a 4000 dpi scanner if it's out-of-focus in places?  Nikon
should hang their collective heads (or themselves!) if this is true.

I guess not many companies use slidemounts that *cause* curved film planes
nowadays (does anyone still produce cardboard mounts?), but I have LOTS of
old K-chromes...
