as others have pointed out, it's parallax error that is causing the problem.
some stitching programs are more sensitive to it than others. PhotoVista
ignores it fairly well in the way it blends. i basically never compensate
for it. other people using other tools sometimes have to be fanatical about
it, getting to within 1 or 2mm of the nodal point or else see strange
artifacts. that's one reason i never use the Panorama Tools-derived
products. all of the ones i have tried are extremely sensitive because they
don't have good blending algorithms.

Rob, I see your point... But I have just one concern here... I tried to
stitch few images shot with 43 Ltd. Prior to that I only used 77 Ltd or
wide end of F 70-210... Apparently when I moved the 43 Ltd every so
slightly I changed the relative position of some elements in the frame in
such a way that stitching became geometrically impossible.
