philosomatographer, You need to wet print 35mm negatives for a few years with, at least Leitz Focomat V35 in order to "get it".
Years ago, Zeiss did very detailed scientific resoultion tests with different films and their Zeiss lenses. The results were published on their website in the camera lens news 17, 19, 20, 24 and 30.
250 lp/mm at f5,6 and 400 lp/mm at f4., Dr. H. Nasse, chief optical designer at Zeiss, has confirmed this on many occasions and in combination with the high res. films that I mentioned earlier such numbers are scientific facts.
Lens resolution is not the strongest side of the larger formats.
