This just started happening with my beloved X-E2. I am not pressing the play button, but sometimes when I hold the body a certain way, it acts like the Playback button is being pressed. At times, it will toggle in/out/in/out of Playback mode. Tilting the camera at a different angle generally stops it. So far this is only happening with the XC 50-230 with some (very light) close-up lenses attached. Anybody else ever experienced this?
