While no one, I'm sure, would argue with your well stated, virtually
axiomatic comments, Alan, it does seem proper to acknowledge that
technology does march on.
Modern designs, using the calculating advantages of the computer,
production techniques allowing less expensive aspheric elements and the
latest coating formulations and application methods do allow a lens with
more elements in more groups to have similar or better results in the
criteria that we feel is important.
What boggles my mind is how good the lenses were when these means were not
available. I love technology, but boy, back in the good old days. . .
