m87501: For anyone considering this camera, I own the EP5 and the simple fix to the trivial shutter shake issue mentioned is to simply use the 1-second delay (or 2 seconds). It's right next to the thumb...easy, solved. It's an ideal camera with wonderful flexible features and image quality for hobbyist landscape shooters like me who can no longer carry a tripod on hikes.
For landscape-only, technical shooting or non-fast action, it would deserve a much higher rating, but I did my homework reading the many helpful & useful tips by those on this forum and others, and knew this going in.
I've shot maybe 1500 pics with E-P5 and never found this issue in my shots. (Haven't been looking for it either) Did a quick review of shots with 1/60 - 1/200 shutter speed and didn't find one pic with the issue. Can't say it doesn't exist, but not so serious problem for me then
