If anyone missed Andy's reply to my original
questions, Go back and read it. Good Stuff.
And yet....
Bill's response strikes resonance with me as
I recall the tremendous power of the analog
computer engineering simulations I was involved
with in the mid 60's at the Edwards Flight Test
Center.
Both Andy and Bill provide valid engineering
points. However, my original concern remains:
Given the developments over the past
twenty or so years in CAD, glass manufacture,
assembly techniques, materials, and mass
marketing, how do the images of today's AF lenses
compare with the classic MF lenses at the same
aperture and focal lengths? Again, comparing
primes to primes and zooms to zooms. My gut feeling
is that we would see the greatest advances in the
area of zoom lenses, provided our "religious"
convictions can tolerate a zoom ;=)

CAD for optical design should be compared with finite element
analysis or computational fluid dynamics to get a feel for the
impact.
