One comment on the 28-70. I've done some testing and at 28mm the edges are sharper f3.5 - 4.5 than at f8 - 11. OSS makes no real difference at f3.5, but does make it a bit less sharp at f8. That make be some of what you are seeing. Since I have an A7, not A7r I can't say about shutter shock at those lengths since I did not see any.

That's why I used it wide open at f/5.6 and 70mm. It's actually sharper wide open. However I've done other tests which show that if you turn OSS off, the overall performance of this lens improves, especially at 28mm.
