Shaky, blurry pictures stink. Especially when shooting in low light without a tripod. Hand holding your DSLR and shooting does contribute to the sharpness of the photo but so does the mirror vibration made from the mirror moving when the shutter fires. To illustrate this point Camera Technica conducted a test to figure out how much mirror vibration there is under certain circumstances. Using a Canon 7D they mounted a laser pointer on the hot shoe and firing the shutter normally, with a finger press, with a remote shutter release and with a remote shutter release and mirror lock up.

I was surprised at how much movement there was from just pressing the shutter with a finger. Which is why I always use a tripod and the timer when shooting low light.
