Thanks, that all makes sense.
I doubt I'd be getting a CIS for the R2000, but knowing it's possible would be nice. It's also nice to know that if microbanding becomes an issue, there is a possible solution. I know nothing about digital negatives, but it makes sense that film would be much more sensitive to microbanding.
I just printed some 4x6 prints for my family of some of the old pictures on glossy. The microbanding is quite obvious on these, and it's not feasible to leave a 1" border. (I usually leave a .75" border on the larger prints. I figure that 1/4" of banding won't be noticed for what I am doing.)
