Yes you are right Ken, but one alternative to this is software correction
for the "distortion". I've read about some great software titles that very
easily remove those charcteristics. I don't know which are best but I'm
sure there are users here that could point you in the right direction.

Thanks Cotty and Henning -
I'm pretty much following you - been chewing on it. Forgive me, this is
the first time I've really tried to get a grip on this question. I think I
do understand what is discussed in Mike's article.
Let me rephrase the question: in 35mm format my favorite w/a is 24mm, not
just because I like the FOV, but also because for me it's the widest lens
that still looks "normal" - wider lenses seem to me to call attention to
themselves as sort of "special effect" lenses. I think even in a
rectilinear lens, there's a lot of keystoning, pincushion and various other
linear alterations. Maybe "distortion" is the wrong word.
So, on a 1.6 format camera, to get the same FOV as a 24mm I need to use a
15mm lens, but on a 35mm camera a 15mm lens is practically a fisheye. If I
take a photo in 35mm with that lens and then crop it in PS by 1.6, those
stretched lines are still evident.
Therefore what I'm understanding - and help me out here - is that the same
thing is going to happen on a 1.6 DSLR, that 15mm lens is still going to be
a 15mm lens with all its innate characteristics, and the only way I'm going
to get a photo similar to the one I take with a 24mm on my 35mm is with a
FF DSLR.
AND, if that's true, is all of the above also true with lenses whose image
circle has been adjusted for the small sensor, as in EF-S lenses?
Thanks for bearing with me here.
Ken
