Yes. I'm less than pleased with it myself, but somehow this "spec" got 
formulated long
ago, and hence film recorders are 2/4/8/16 K
It's certainly not *my* definition :-)

Agreed, but I should add that I can see no real diff, rez-wise, with loupe 
either.
There is always a *slight* diff, contrast/color balance etc, because there are 
so many
variables in the scan itself and tweaking in image editor. Much like even a 
"perfect"
slide dupe.

Yeah, didn't push the envelope, so couldn't say. Might not have been 
discernable diffs
even then.  Could have gone 20" too. 'Course, many photogs, myself included, 
would
say that 35mm is not suitable for 16x20" period.

Once I upgrade to scanner that *can* do the "4K" rez, I'll run all my tests 
again, for
me, and keep the results.

Oh, I'd think at least 8x10. Again, assuming we can have digicams with at least 
as
true a pixel quality as some current film scanners.

Oh, for majority of my digital output, I shoot 90% film, whether location or 
copystand
and scan. I'll use my 3MP Kodak 4800 for visiting Mom this weekend, eBay 
auctions,
some website usage, etc. And really, if this camera were capable of capturing 
11 to
12MP, but only with same individual pixel level quality as now, I don't think 
that
practice would change much.
