In many cases, it is tough to envision the gap between sensor measurements merely by going over specs. The visual here should provide you a greater sense of the sensor dimensions in the 20D and D7100.

As you can plainly see, both of those cameras feature the identical sensor size albeit not the same megapixels. You should count on the Nikon D7100 to offer greater detail because of its extra 16 Megapixels. Higher resolution can also help you crop photographs way more aggressively. The older 20D is going to be disadvantaged with regard to sensor innovation.
