I bought a used E-M5 on eBay in Australia. The camera looked and worked great unit I discovered that the shutter was malfunctioning at high speeds (1/500 and above): I would get black images. While not a totally uncommon problem (web search) I was fearing my camera was not going to be fully useful: repairing the shutter would cost hundreds of dollars. The person that sold it to me was unaware of the problem but was able to provide the receipt from the Australian (legit) store he bought if from. Olympus Australia repaired the camera under warranty since it was sourced from an authorized retailer (no grey import) and even replaced the missing eye cup for free. As long as the warranty is still valid (2 years) Olympus equipment can be sent in for repair for free. The warranty is transferable. Needless to say that suddenly increases my liking of purchasing used Olympus equipment if it is relatively new, as prices on eBay are so much cheaper than new. I have now bought several M.Zuiko lenses, all used. Luckily lenses seem to be less finicky with less things that can go wrong.
