The GF1 was manufactured 5 years prior to the K-S1 which is a fairly big gap as far as camera technology is concerned. Both the cameras offer different body type with the Panasonic GF1 being a Rangefinder-style mirrorless camera and the Pentax K-S1 being a Mid-size SLR camera.

Before delving straight into a detailed comparison, below is a quick introduction of how the GF1 matches up against the K-S1 in the way of portability, imaging, features and an overall mark.

Normally, it is tough to see the contrast in sensor dimensions purely by going through specifications. The image here might offer you a far better sense of the sensor dimensions in the GF1 and K-S1.

Plainly, the two cameras offer different resolutions and different sensor dimensions. The GF1 featuring a smaller sensor will make getting shallower DOF more difficult and the Pentax K-S1 will provide greater detail due to its extra 8 Megapixels. Greater resolution will allow you to crop images a little more aggressively. The more aged GF1 will be disadvantaged when it comes to sensor technology.
