Digital BW, The Print

If you read the article, it says the following:

"Kodak had suggested that a photographic lens needs to have a resolution 3
times as high as that of the film to fully exploit the capabilities of the
emulsion."  It's apparently not quite true, but never the less, a good
starting point.

So, even at 40 lp/mm, that's a lense of 120 lp/mm...  He also says that the
best photographic lenses from Leica can achieve 250 to 300 lp/mm...so as I
said, there are lenses readily available that easily accommodate high
resolution films, even if you take the 3x "rule of thumb" or not.
