Sorry Steve, I dont believe this is correct. Magnification should
have nothing to do with it. Its simple geometry. Imagine a line
right down the center of the focal area, now move that line in a
parallel way some distance, i.e. 1mm. The entire line, being
parallel, by definition is 1mm apart from infinity to infinity.
Assuming the line corresponds to a beam of light, you *can't* move it in
a parallel way. If it's straight on-axis (which the light will be, if
the lens is symmetrical about its axis) it'll be bent off-axis. That's
what lenses do - they bend light.
Yes, you are correct if we are talking about moving only the sensor,
which of course the antishake mechanism is going to do. In my original
posting and above also, I was referring to the whole lens/body combo,
which would keep the geometric consistency about the axis the way I said
above. Sorry about the confusion.
