So I got my new E-M10 and soon after noticed a weird rattling sound coming from it whenever I gently shook it or put it down on a surface..or even just moved it upside down. First I thought it was from the attachments to the strap, so I took both of them off, since I'm not gonna use them anyway. But still the rattling sound continued. I Googled it and found some threads about something similar, including on this forum Apparently it was the sensor shifting around, and indeed the sound did diminish a bit when I turned the camera on. But even with the camera on and the IBIS active, there was still this annoying sound when I moved the camera. I then popped up the flash and noticed that the sound was coming from there! Inside the flash, there are two long silver plates, which are connected to the pop-up mechanism, they were loose and causing the rattling. The screws are quite small, and I didn't have a proper screwdriver to tighten them. Normally, I would send it back to the shop to get it fixed, but currently I can't go without the camera, since I need it a lot in the coming weeks. So I used some tiny pieces of paper and jammed them in between the silver plates and no more rattling The flash still works fine, but if I pop it up normally, the paper pieces fly out. It looks cool but it's impractical If i pop it up gently, by holding it with my finger, the pieces stay in place. I'm probably gonna have to get it fixed properly at some point, but for now it's a good enough workaround. I couldn't find anyone else with this exact problem, but if someone else should somehow stumble upon this via Google, I hope this is helpful! Picture attached showing the metal plate and the paper I jammed in there.
