If you are having a vibration problem, then your tripod is not adequate to the task. You are using a tripod, not hand-holding, yes?
I use a massive Majestic tripod that could easily support my car for an oil change. Get a better tripod.
Your claim that the relatively slow movement of a set of shutter blades that weigh maybe 5 grams would cause
vibration in a lens assembly that weighs 1250 grams simply doesn't work mathematically.
