While Leica has yet to announce a compact system camera (CSC), it is one of the few companies to offer a compact camera with an APS-C format sensor. Its first model, the Leica X1, has now been replaced by the Leica X2. The major changes that the Leica X2 brings are the upgrade from a 12.2 million effective pixel CMOS sensor to a 16 million effective pixel device. This is a considerable jump, so it will be interesting to see whether it has much impact upon the camera's ability to resolve detail and the level of noise present in images.
