B.D. I use too a AFS 17-35 and my main concern, if there are not many
buildings or straight lines, is not distortion that by the way is rather
big, but strong flare and vignetting. My M 21 ASPH works much better in this
field. I'm awaiting the new Vario Elmar 21-35 R and a as soon as I get it,
besides shooting on the field, I'll test comparatively M21, R21-35 at 21 and
AFS 17-35 at 21. I can foresee in advance the results, unless some big
surprise, buth then when some one ask about this comparison I'll give an
opinion based on facts not in names or brands. Today exactly my wife is
declared by doctors, after 4 months, as absolutely cured, she was at home
but not allowed to work,  so I believe that very soon I'll be able to offer
some pictures to the LUG as I shall have more time.

Kind regards

Felix
