Ummm, don't forget, folks, that most of the shake comes with
the mirror return (after exposure, when you may see a jittery
image, and the end of the lens move), and not when the mirror
flips up and the shutter opens (to check this out, hold the
camera while releasing the shutter [set for 1 second] - you
can feel at which end of the exposure most of the shake occurs).
Hope This Helps
