Like many users I was positively surprised by the quality of photos taken with the RX100. This is undoubtedly one of the best in its class. Moreover it is small and light. That's why I chose it. I can take with me often. BUT after 8 months of careful use, I dust on the sensor that requires me to correct almost all my pictures in post production. A peak for a product of this price which moreover do not change the lens. By searching the internet, I quickly realized that I'm far from the only one with this problem. Finally, I strongly recommend buying this device. The guarantee .. by having bought from "gadget magazine" I realize that there is no guarantee. Gadget does not respond to my emails or those of Amazon. In addition the unit from china, it does not benefit from the guarantee offered by European Sony. SECOND CONCLUSION never buy anything Gadget Magazine.
