In other words, 35mm film photography has basically reached its peak of quality - if you want better, you need to change format and/or capture technology.

LOL! Was only looking over at the S2 to ask, why? honest...

Thanks for the great reply - much more technical evaluation than I was expecting - welcomed though.
Interesting that that your assessment of "new" style 35mm lenses will give little quality gains over "old" style lenses, sort of what I had been thinking; gains there may be but not quantum leaps in quality. The technology of film (grain size) being the limiting factor - the new lenses may outperform the technology of film but tightening up of edge sharpness etc may be of benefit to a 35mm shooter.
Would love to see a direct comparison shot between say a Hass 120 lens and a Canon 85/1.2 for instance (or comparable portait type lenses) on film stock - just for arguements sake!
Thanks for the input.
