One of the things that is very noticable about the hundreds of handheld images seen thus far from the a7r is the near total absence of definition loss, even at 100%.
We of course need to be attentive to this issue, but Sony have an excellent record as they know their cameras will be used (inter alia) as high end image producers, it's been that way since the landscape oriented a900. Until last week I had never heard the term 'shutter shock', and it was not in connection with a Sony camera. You are also the first to report this occurrence, so the burden of proof rests more heavily upon your shoulders.
Certainly such claims need to present convincing methodologies in support - as in repeatable sets showing the same phenomenon and isolation or adjusting for extraneous variables that, as Tariq suggests, may explain what is seen.
'Vibration of the A7r is clearly showing up from 1/125s to 1/2s.'
Where are the rest of these images? I saw only two side by side. Do you claim both are affected, to a differing extent?
How well was the tripod anchored? ...a lot of people operate under the illusion that a few kgs of combined pod/head/camera/lens is sufficient to stabilise the platform under all circumstances - it isn't. I can provide a white paper on this if needed.
So thus far I find the statement: 'Vibration of the A7r is clearly showing up' far from statistically proven. There are other factors - few people shoot bank notes for either a living or for fun. You could try more typical subject matter with a resulting higher chance of persuasion. Finally, you could include in the 'test' your preferred reference setup, whether a D800e or similar - to at least indicate what the target performance might be, what is fair to be expected...so 'an open mind but need more information'.
