Tom, I'm not so sure that this is uniformly the case. There are some very high-end film scanners that can do 10,000 dpi optical (the Linotype-Hell S3900, for example). Most of us are not willing to pay what it costs to have our film scanned on these scanners, but their resolution is sufficient to capture very fine detail -- it's somewhere in the neighborhood of what Technical Pan can resolve. If one has two exposures that show differences in lens quality, then one can show that on the Web by showing small portions of the scan on a Web page. - -Patrick
