This is an interesting scientific experience with a Laser attached to the flash shoe of a camera.
It is to explain that there is not possibility to have a perfect clean picture on a camera without a tripod (in a shutter speed under ~1/400). Well, this experience forget to talk about different stabilization technology. But, it is interesting to see the difference with the mirror lock up.http://www.engadget.com/2011/05/03/lasers-prove-you-cant-hold-a-camera-still-video/

I think this is where the Minolta Technology (now Sony) has advantage on this kind of vibration, because the software can acts exactly at the good moment to remove the shutter vibration from the mirror by moving the sensor (where a in lens stabilization cannot move enough fast lens element to compensate, and when this stabilization is available on the lens -> no prime except for new lenses on the market like the Canon Macro).
