I'm not sure you ever read his books or newsletters either, Mark.  Had
you
done so, you would know he suggested longer lenses would produce a more
even
image.  He had it on good authority.  Saint Ansel, Book 3, Page 29
[later
series] said:  "The lens must also "cover" the negative area with
minimal
fall-off at the corners. Using a lens of longer focal length
than"normal"
will help avoid this fall-off of illumination; it will also help ensure
good
definition at any aperture, since only the central portion of the lens's

field of view, where resolution is highest, will be used. ..."

Sorry, Mark, but he makes lots more sense than your ranting!

Alec,
This was true 40 years ago. Ansel Adams died nearly 20 years ago now.
Update that cult.
