From time to time I read funny stuff here.
Let's put things in the right perspective: if we talk about defending our low-budget purchase because we can't/don't want to buy a high end scanner, good.
We're not made of gold; I'd love to buy a Leica MM but can't and won't.
I'd also love to have an Hasselblad X1 for 35mm + a Kodak IQSmart3 for larger formats, but can't and won't.
But trying to push that a flatbed scanner is "perfectly fine", or even that 3200 DPI are all that's needed... frankly, let's be serious.
I won't publish scans of charts because I don't want to be boring; instead, I'll show you the pixel-level crop of a small portion of a scan of a 645 frame (Fujifilm Provia 100 positive film).
It's an old picture (10 years old) taken with a battered camera (Pentax 645, first version) which does not even have mirror lockup. So it's not the sharpest medium format shot ever made.
Even then, see how a drum scan (left) resolves more REAL DETAIL than a Nikon Super Coolscan 8000 ED (4000 real DPI).
An expert won't need any more information to understand my point.
For the less expert: yes, the 11000 DPI scan from the drum scanner shows more noise/grain, it's normal. And yes, it has some small defects due to the age of the machine.
Yet, the 4000 DPI (!) scan from the Nikon just CAN'T resolve the real details on the conditioner's shell.
This means, yes, that an average, not top-class medium format frame shot on 100 iso positive film CAN have real details a 4000 DPI nice-working scanner can't resolve.
Now just think about "Leica Summicron" and "Velvia 50" or "Agfa Copex Rapid" and think again about a 3200 DPI scanner being "more than enough".
