The K-S1 was introduced 2 years later than the W650 and that is quite a large difference as far as tech is concerned. Both of the cameras have different body design with the Pentax K-S1 being a Mid-size SLR camera and the Sony W650 being a Compact camera.

Before we go straight to a comprehensive comparison, here is a simple summation of how the K-S1 scores against the W650 in relation to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Pentax K-S1 & Sony Cyber-shot DSC-W650. The whole galleries are provided at Pentax K-S1 Gallery & Sony W650 Gallery.

Usually, it can be hard to imagine the difference between sensor measurements merely by reading a spec sheet. The graphic here may give you a stronger sense of the sensor sizes in the K-S1 and W650.

As you can see, both of these cameras provide different resolutions and different sensor measurements. The K-S1 with its larger sensor is going to make achieving shallow depth of field easier and the Pentax K-S1 will offer greater detail using its extra 4 Megapixels. Greater resolution can also help you crop pics more aggressively. The more modern K-S1 should have an edge in sensor technology.
