I'd even say that the lens is not the real issue. The shutter is. 

I've taken a couple of hundred images back there during the vacation in New Zealand.

Subjectively more than half of them show a suspicious degree of overall blur that cannot be explained by the lens nor the shutter speed.

The A7R will certainly start collecting dust in my closet except for those occasions where I have to use it for testing purposes.

 

I used the A7r for two weeks in Cuba recently without blurry pics. 

All handheld mostly 1/500s to 1/2000s.

 

Could you please tell us the speed and conditions (tripod/no tripod) of your photos?
