I have the 1st gen Konica-Minolta 5400.
Oh, I forgot. The 5400 has something called “Grain Diffuser”. It is used to reduce the film grain. It is a hardware/software solution and works fairly well, at the expense of increased scan times.
The Nikon has something similar called Digital GEM, which, I think, is software-only.
Here’s a kicker – you may have heard that KM is getting out of the camera business by selling the camera line to Sony. It became effective April 1. I’m pretty sure that includes the scanner line. I’m not sure you can even buy a 5400 anymore.
I hear real nice things about the Nikon line… 😉
