3 Weeks of OM-D, 3 Weeks of Rubbish

I get shutter shock, if that's what it is, primarily in Aperture priority and often in low light.  Its not every frame, but there are many where I see this.  I also get it only on auto focus lenses.  With legacy lenses, I can be out of focus but I don't see shutter shock.

Switch the mode dial to Auto, SCN, Art, or P and I don't see it.  Haven't tried Shutter Priority or Full Manual yet.

Anyone else observe this?
