I had a long conversation with one of our more famous camera makers, and he said that if one is using f16 or smaller, the new lenses do nothing for you in terms of image clarity or sharpness. We did not get into acutance, and other things that are somewhat subjective, but it leaves me with the question. Why would you pay $1800 for a new model schneider that is available as a goertz or eastman in the used market for $500? I am speaking of mid length 5x7 lenses, say 180mm to 270mm. This question makes the assumption that the lens design is the same, i.e. same number of air contact surfaces and a basic design, say a tessar.
