Lets look much closer at the Leica X1 versus Leica X2, both Large Sensor Compact digital cameras and they are both created by Leica. There is a sizable difference between the image resolutions of the X1 (12MP) and X2 (16MP) but both cameras provide the same sensor sizing (APS-C).

The X1 was brought out 3 years earlier than the X2 which is quite a significant difference as far as tech is concerned. Both of these cameras have the same body design (Large Sensor Compact).

Before going right into a detailed comparison, here is a simple introduction of how the X1 grades against the X2 with regard to portability, imaging, features and an overall mark.
