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.


I experienced the same thing with Olympus but the IS effectis separate from the shutter shock issue. The. Effect although similar in appearance (slight blurriess) is independent one from the other. Common sense dictates that IS (OSS) should be OFF when using a tripod, there is no need or it.
