Oftentimes, it is tough to imagine the difference in sensor sizing simply by going through a spec sheet. The graphic underneath might give you a greater sense of the sensor sizing in the DP1s and TX55.

Clearly, both of these cameras have got different resolutions and different sensor sizing. The DP1s because of its larger sensor is going to make achieving shallower depth of field simpler and the Sony TX55 will show extra detail as a result of its extra 11MP. Greater resolution will make it easier to crop pics much more aggressively. The older DP1s will be disadvantaged when it comes to sensor innovation.
