Sometimes, it is difficult to visualize the contrast in sensor dimensions purely by going through specifications. The image here should provide you a much better sense of the sensor dimensions in the G1 and K-7.

To sum up, both cameras feature different resolutions and different sensor dimensions. The G1 using its smaller sensor is going to make getting shallower DOF more challenging and the Pentax K-7 will show greater detail having an extra 3 Megapixels. Greater resolution will also enable you to crop pics way more aggressively. The more aged G1 will be disadvantaged in sensor tech.
