[buster3000]

I have that scanner you're talking about and a Nikon V ED. The Nikon with 'only' 4000dpi massively out-resolves the V850. It's true resolution is somewhere just over 2000dpi and that's after adjusting the trays height.

Because of that I only use the V850 for 4x5 and 120. It's a waste of time for 35mm even if it's quicker to scan multiple frames.
