Usually, its tough to visualise the gap in sensor sizes merely by viewing a spec sheet. The picture here should offer you a far better sense of the sensor sizes in the DP2 and A55.

Clearly, both the cameras come with the identical sensor size albeit not the same megapixels. You should expect the Sony A55 to render greater detail due to its extra 11MP. Higher resolution will allow you to crop pictures a good deal more aggressively. The more aged DP2 will be behind in sensor innovation.
