Sometimes, it is very tough to visualise the contrast between sensor sizes merely by going over specs. The pic below might offer you a far better sense of the sensor measurements in the DP2x and A550.

As you can plainly see, both of the cameras have got the exact same sensor measurements albeit not the same megapixels. You should count on the Sony A550 to deliver more detail due to its extra 9 Megapixels. Higher resolution will also enable you to crop shots much more aggressively. The more recent DP2x will have an edge with regard to sensor technology.
