To successfully assess DSLR scanning capabilities I needed 35 mm film which would not be outresolved even by the high-end  digital camera. Of all the chart pieces the real drama happens right there - in parlance of USAF 1951 - at Group 0 (zero). Say, if Group 0 Element 5 to be resolved, the lens +film resolution should be at least 87 lp/mm (calculation are based on my USAF targets dimensions and the shooting distance/lens focal distance). Just think of it - you are in front of a chart 24x36 inches (60x90 cm) at normal viewing distance - say two feet - will you be able to see the strokes of size 0.3 - 0.5 mm ?

Even if film+lens give us say 90 lp/mm what your digital camera will be able to capture? Read on... Even half a year ago, I was not familiar at all with the films sold nowadays in American stores.
