Came across this article which I would like to share.
"Because blur due to lens movement is inevitable at any shutter speed slower than 1/1000 sec., and because it promotes greater care in composition. Handholding is strictly for dead photographers: A human pulse beat will cause 200 microns (about 0.008 inch) displacement for 1/10th second. Assuming a shutter speed of 1/250th sec., this movement alone will cause a 22% loss of resolution with a system that is otherwise capable of reproducing 100 lines-per-mm (lpm). And at a shutter speed of 1/125th sec., this performance would degrade to only 53 lpma 47% waste of what you purchased. (Refer John B. Williams: Image Clarity, page 191)"
Agreed? Comments are welcome.
