The Sony A7R lacks an electronic first curtain (EFC) shutter found in its sibling, the 24MP Sony A7 (electronic first curtain shutter = zero vibration exposures).
The laws of inertia and physics do not allow acceleration (shock/vibration from the shutter) to disappear, but F = mA has a mas components that implies that if the mass increases for the same acceleration (shutter vibration), then the displacement ought to be reduced. By simple math it has to work, the only question being how well.
And so I wanted to know whether a simple way to mitigate the shutter vibration by adding mass to the system would work—something easily done and not requiring elaborate measures.
