I'm fairly surprised by the lack of more visible shake all round. It looks as if making three or four exposures with the shutter speed set slightly above the focal length rule (1/80th-1/100th here at 70mm) will in my case produce at least one clean result.

There shouldn't be any clean results if your alleged shutter shake is real. How do you explain a clean result with shutter shake? The earth moved just the right amount to counterbalance the camera shutter at the exact moment maybe?

If you have any experience of cameras in general - I have in all formats from subminiature to 10 x 8 including some of the worst shutter-mirror shake offenders ever made, like the Bronica C - you'll know that hand-held results

Ok I had figured you at least used a tripod with those shots. If they were hand held they're utterly worthless for any kind of shake test, I can't imagine why you even bothered.

This issue has been tested to death with tripods. They offer repeatability and tend to show the shock quite consistently in specific shutter speed range, 1/100 +/- some depending on the lens over 100-150 mm, depending on lens weight/dimensions.

Handheld is equally interesting; there have been findings suggesting that heavy lens + handheld is not affected by the shock (LLoyd Chambers). Mushy human body is not that good at transferring vibration and heavy/sturdy lens propably absorb some. Then there is the question of whether or not IS is help or liability here (IMO it looks like it can be either as I'm getting good results with my 100/2.8L IS shooting shutter speeds in the middle of problem range.) and that obviously means handheld testing.

I have questioned Lloyd Cambers' work on his issue before. Formerly a respected researcher, he seems now to be part of a movement to demonstrate tthe Olympus E-M1's superiority over the Sony FF cameras. Be that as it may, these reports from Lloyd and Kirk on this issue is questionable to he extreme. Again, there is no solid evidence of SS with the A7r.

Lloyd Cambers if you read his website more is not even keen on m43. To say he is now part of a movement to demonstrate it's superiority over the Sony FF cameras is laughable. He actually like the A7. If he was against the system he would be bashing both cameras.
