Well done TimSo: this might be that I have a poor copy, it might be that the lens is just too humble to stand up to the A7R, or it might be that some of its design compromises are showing and, when learned and understood, can be worked around.
for what it's worth, I just shot 55 more shots on the A7 (funny that, I'm obviously a 55 shot man), without a single shot out of focus - some were grab shots of running dogs, some long distance etc. etc.
I think that as someone else suggested, it might be the PDAF sites on the A7 which is the issue?
