The RX1 is an amazing camera, but I would not buy it. Sony has a history of putting out high concept, generation-ahead-of-the-industry, one-off products at silly prices. Usually, they are precursors for better realized, less expensive, main line models. Within a year or so, they will probably be selling full frame mirrorless cameras with OLED viewfinders and interchangeable lenses--at a lower cost. According to gossip amongst those who follow the company, they are planning a broad assault on Canon and Nikon with several new, innovative full frame options. They've specifically stated a full-frame NEX camera is possible. Wait.
