Before getting straight to a detailed comparison, here is a quick introduction of how the G1 matches up vs the K-S2 in the way of portability, imaging, features and an overall mark.

Here is a preview of the gallery images for Panasonic Lumix DMC-G1 & Pentax K-S2. The whole galleries are provided at Panasonic G1 Gallery & Pentax K-S2 Gallery.

Usually, it can be tough to visualize the difference in sensor dimensions merely by researching a spec sheet. The image here may give you a much better sense of the sensor measurements in the G1 and K-S2.

Clearly, both of those cameras come with different megapixels and different sensor dimensions. The G1 using its smaller sensor is going to make getting shallower depth of field harder and the Pentax K-S2 will provide you with extra detail with its extra 8 Megapixels. Higher resolution will also make it easier to crop pictures a good deal more aggressively. The more aged G1 will be behind when it comes to sensor innovation.
