Oftentimes, its difficult to visualise the contrast between sensor sizing just by reviewing specs. The graphic underneath may give you a stronger sense of the sensor dimensions in the D40X and A55.

All in all, each of the cameras offer the same exact sensor sizing albeit not the same MP. You should count on the Sony A55 to deliver extra detail because of its extra 6 Megapixels. Higher resolution can also help you crop shots a little more aggressively. The older D40X is going to be behind with regard to sensor tech.
