The SZ1 was manufactured 3 years earlier than the K-S1 and that is quite a sizable difference as far as technology is concerned. The two cameras have different body design with the Panasonic SZ1 being a Compact camera and the Pentax K-S1 being a Mid-size SLR camera.

Before getting into a in depth comparison, here is a brief highlight of how the SZ1 scores vs the K-S1 with regards to portability, imaging, features and an overall rating.

Typically, its difficult to picture the difference between sensor sizing simply by reading through a spec sheet. The visual underneath might give you a much better sense of the sensor dimensions in the SZ1 and K-S1.

Clearly, the 2 cameras provide different resolutions and different sensor sizing. The SZ1 featuring a tinier sensor is going to make getting shallow DOF more challenging and the Pentax K-S1 will resolve extra detail due to its extra 4MP. Higher resolution will allow you to crop pictures more aggressively. The older SZ1 is going to be behind with regard to sensor tech.
