Re: "sh_tter Shock": multiple cases and causes?

Great term! Especially the "fill-in-the-blank" missing vowel between 'h' and 't'.

Putting a 'u' in there, and reading the numerous posts about it, quite a few hypotheses have been put forward that might account for unexpectedly blurry images. So it seems not a settled issue.

Whenever there's multiple "explanations" for something, leads me to wonder if there's more than one thing going on. Perhaps the "cause" of blur is different in various cases. Disentangling which is which may not be so easy.

So it's conceivable the problem could be "shutter button jab", shutter vibration, IS or AF mechanism "looseness", other factors not yet teased out, or >=2 of these at the same time.

As a side note, it's good to see this being investigated rather calmly and patiently, without "hysterics" that sometimes have been evident with other issues.

I've had instances of mysterious blur with the E-M5, but I've just started to review the situations re: lens, shutter speeds, etc., and consistent patterns not yet emerged. However, I'm going to keep looking at it, and maybe will have more to report later.

If you search for "shutter shock" on this forum (which you potentially might do even more effectively via google than the internal search function), you will encounter a large number of prior threads on the subject as well as quite a few tests. Many of the comments in the threads on the subject that have surfaced during the past few days are poorly informed because the posters aren't informed about what has been said and done in the past. In reality, I think we have a pretty good understanding of what's going on and not.

Here's an example of fairly recent thread (two months ago) which contributes some new tests as well as links to previous ones:
