I did the test here: http://beforethecoffee.com/sony-a7r-vibration-comparison-with-nikon-d3-and-sony-nex-7/

I took 30+ sample images, one set with no shutter vibration and one set with normal shutter vibration exposures. Then I compared the results. I used a Nikon 85mm 1.4 and the Sony FE 35mm 2.8.

I am very pleased to find no visible evidence of shutter vibration in images from the A7R when mounted on a good tripod.

Well done ferrellmc!

This test data directly addresses the issue, ie image blur. No need to be concerned how some intermediate type of measurement relates to the issue.

After having put forth this amount of effort it would seem appropriate to extend it to determine your own min shutter speed rule of thumb. If you have not already done so, consider shooting some hand held comparison shots to establish just how steady you are.
