Often, its hard to imagine the contrast between sensor sizes merely by going over a spec sheet. The picture underneath should give you a stronger sense of the sensor measurements in the E-1 and K-7.

As you can see, both the cameras provide different megapixel count and different sensor sizes. The E-1 because of its tinier sensor is going to make getting shallower depth of field more difficult and the Pentax K-7 will offer greater detail as a result of its extra 10 Megapixels. Higher resolution will help you crop photographs more aggressively. The more aged E-1 is going to be behind with regard to sensor tech.
