I read the shutter shock comparison test here, and it seems like it's a pretty significant problem with the E-PM2 when using shutter speeds in the 1/80 to 1/160s range. https://www.mu-43.com/showthread.php?t=35882 I have a few questions about the issue: 1) Does shutter shock only affect certain lenses, or is it the same with all lenses? 2) Would disabling the IBIS eliminate the shutter shock issue? 3) If I use a lens with built-in IS (e.g. PM2 + Panasonic 12-32mm pancake), would that combination still be affected by shutter shock?
