Generally, it is very difficult to picture the contrast between sensor sizes merely by reading specifications. The image below might provide you a far better sense of the sensor sizing in the G1 and K-30.

Plainly, the 2 cameras have different megapixels and different sensor sizes. The G1 using its tinier sensor is going to make achieving shallow depth of field more challenging and the Pentax K-30 will offer you more detail using its extra 4MP. Greater resolution will also enable you to crop images a bit more aggressively. The more aged G1 is going to be behind in sensor tech.
