I have heard about problems with other systems too. But with those I have personally used (Pentax SR, Panasonic OIS, Olympus IBIS as implemented in the E-M5), I have never found any indication that keeping the system on when at shutter speeds so high that it isn't really needed has any adverse effects.

I am intrigued by IS on leading to bokeh being worse. What would be the mechanism for that?

I will do some systematic tests when I get the time. Very interesting.

Perhaps slimandy knows more. But one guess is that the bokeh is best when the IS lens group is locked in center position. Even if that lens group doesn't really move during very short exposures, it might be slightly off center due to what happened immediately prior to exposure.
