Currently my two months old Olympus XZ-10 is at Olympus for cleaning the sensor after I noticed some dust and returned it to the shop where I bought it. It will take about 4 weeks As far as I know it will be done under warranty. I asked both Olympus and Panasonic about there warranty/repair policies in case of dust on the sensor in a camera with a fixed (zoom) lens. Olympus says it is not normal that dust will reach a sensor under normal circumstances and that they will investigate case by case if they can clean it under warranty. Panasonic won't give a clear answer which give me not much in buying a camera like the DMC-FZ1000 or DMC-LX100. Now I'm interested in real world experiences on how a dust on a sensor in a fixed (zoom) lens camera issue was solved by different brands. What brand offers the best service in a case like this?
