Normally, it is very tough to visualize the gap in sensor sizes merely by looking through a spec sheet. The picture here may provide you a stronger sense of the sensor sizes in the DP1s and A58.

Clearly, each of the cameras enjoy the same exact sensor sizing albeit different megapixels. You can count on the Sony A58 to render greater detail as a result of its extra 15MP. Higher resolution will also allow you to crop photographs far more aggressively. The more aged DP1s will be disadvantaged when it comes to sensor innovation.
