Often, its difficult to imagine the contrast in sensor dimensions just by checking out a spec sheet. The pic underneath may provide you a clearer sense of the sensor sizing in the 30D and K-7.

As you can see, the 2 cameras have the same sensor dimensions but different megapixels. You should expect to see the Pentax K-7 to produce greater detail using its extra 7 Megapixels. Greater resolution can also make it easier to crop photos a bit more aggressively. The more aged 30D will be disadvantaged in sensor tech.
