That's pretty close to my impression, too. But the SS4000 doesn't
deliver a real 4000ppi, either - there is a certain amount of bleed.
Compare a scan from the SS4000 with a 4000ppi drum scan.
It's a pretty nice scanner, though - I'm still considering one.
But you have to be trying pretty hard to get that information out of
the film - you need a really good lens, and a rigid camera plateform.
If you are hand-holding the camera you won't get anywhere near that.
And even the best zoom lenses fall far short of the requisite lpi.
I think that the next round of digital cameras (4 megapixels and up)
will begin to edge into serious consideration for replacing point-and-
shoot cameras for all purposes - the image capture stage will no longer
be the weakest step in the process.
For all but the most demanding uses, I think 24 megapixels (4k x 6k)
will suffice to replace film. That's about the resolution I expect
to push 35mm off the market almost entirely - the few people who need
more than that will migrate to medium format for quality purposes.
