One small point
In reply to Anders W, 9 months ago

Overall, it seems to me that the only real point of disagreement left is that I don't think the specific vertical double-image I see with the E-P5 comes from the same mechanism as the 'shutter shock' images I have - the blur is just so much stronger. Here there's one specific point worth discussing:

However, what you said about your own test results in a prior post (i.e., that you see the same blur with the E-P5 when you shoot with as much as two-second self-release or anti-shock delay) rules out, to my mind, the possibility that it is the shock due to button-pressing that is the culprit. As far as I can see, there is no way the "shock" due to button-pressing could last as long as two seconds.

Equally, though, if the shake were due to shutter shock, it should be just as 'fixed' with 2 second anti-shock as it is with 1/8 second. In practice, 2 second anti-shock gives just as much shake as 2 second self-timer. That's difficult for me to fit with a shutter shock explanation.

At this point, while there are certainly other tests which could be done to try to pin things down, it starts to look like a lot of time spent for minimal benefit. What matters here are the two simple observations - the E-P5 seems unusually prone to producing blurred images, and the anti-shake setting looks like an option worth trying for users who notice this and consider it a problem.
