As you can plainly see, both cameras enjoy the same exact sensor sizing albeit not the same megapixels. You should expect the Nikon D5000 to result in greater detail having its extra 6 Megapixels. Higher resolution will make it easier to crop shots far more aggressively. The younger D5000 will have an advantage with regard to sensor technology.
