I would seldom venture to correct you Ron, but I think "the trick" is
for the photographer to learn technique, and stabilize the camera.

Well heck... Even if they DO have IS, it helps to use basic stabilizing
technique.



Pretty much on point!

IS makes it too easy to "blow off" the basics of bracing and stance, and
using common objects to stabilize the shot.

If you dont learn these things, you stand a good chance of "blowing"
some good shots even if you do have IS, because IS is not the "be all"
and "end all" of long lens photography.
