Now compare that with the 330 lines per mm you get from a typical
apo-lanthar or apo-tessar as were made back in the '30's . . .

   Looking at a
polaroid (I managed to get one within the last
 few minutes), I think the usable resolution is way more than
 1200 pixles per row (say more than 200 lines per inch). 
I've just realised...

If you have a 100mm wide print (normal sort of size) and 640 pixels,
that's only 3 or 6 lpm (depending on whether you think a line is 1 pixel
or 2). That's not a poor resolution, it's a non-existant resolution!

Ouch!. Now I know why I can't stand those digital cameras.
