Hi, Much is made these days of the performance of modern digital lenses in this respect. I am interested to hear what you consider to be a limiting value in terms of pixel width. Are you bothered by it or do you just accept that it is there and ignore it? Do you worry if it can only be seen when pixel peeping? I have a few legacy film lenses, which I consider to be of acceptable quality and it has always been my assumption that, because this flaw cannot be corrected with film, film lenses were more carefully designed to correct this than some lenses designed for dslr's. Am I wrong, or is it again a function of price? How good is software at dealing with it?
