I've at times thought to use seismometers to measure the vibratins from different cameras - being a seismologist.
That's an interesting idea but I'm not sure if it'd be very accurate. For an accurate measurement of the vibration that actually affects the image you'd have to only measure the vibration while the shutter is open.
These instruments can measure the exact frequencies of the vibrations and one could have a deterministic measured value and not just guesses which are based on how solid/loosely camrea is fixed to tripod or hand. Maybe I'll make a test within the next few weeks of this?
It'd also depend on the tripod itself. I've heard that wooden tripods are far superior because they actually damp the vibrations, where metal legs will just ring at their resonant frequency.
