Thanks, Jan. Terry on the list sent this article link that is quite
thorough:

I'll go ahead and calibrate for the range of lengths. I like lots of
sharp details, so I love to zoom in as far as possible and shoot a lot
of frames covering a view, instead of zooming out.
I have a friend that always responds to my panoramas by saying, "Why
don't you just buy a wide-angle lens instead?" But then, he thinks my
interest in producing 10-12-foot long panoramas at 300DPI is silly. 😉

Yes.
Things like distortion, vignetting, and front nodal point all change
with focal length on many (most?) zoom lenses.
For panoramas, I'd calibrate for the widest zoom setting, since that's
what you'll probably be using.

Good afternoon!
I have five lenses I mostly use. One is a prime, another is a
500mm tele.
The other three are zooms.
When calibrating zooms, do I need to calibrate separately for the
different zoom lengths?
Thanks!
