More often than not, it is hard to visualise the difference between sensor dimensions merely by going over a spec sheet. The pic underneath might give you a better sense of the sensor dimensions in the D40X and A390.

Clearly, both of these cameras offer the same exact sensor sizing albeit not the same megapixels. You can count on the Sony A390 to offer more detail having an extra 4 Megapixels. Higher resolution will also make it easier to crop shots a little more aggressively. The more aged D40X is going to be behind when it comes to sensor innovation.
