The S1R was released 10 years later than the K20D and that is quite a big difference as far as tech is concerned. Each of these cameras come with different body type with the Panasonic S1R being a SLR-style mirrorless camera and the Pentax K20D being a Mid-size SLR camera.

Before diving in to a in depth comparison, below is a brief summation of how the S1R scores versus the K20D in the way of portability, imaging, features and an overall grade.

Often, it is tough to see the difference between sensor measurements simply by reading specs. The visual here might give you a much better sense of the sensor dimensions in the S1R and K20D.

As you can plainly see, both the cameras posses different megapixels and different sensor measurements. The S1R featuring a bigger sensor will make shooting shallower DOF simpler and the Panasonic S1R will offer you greater detail as a result of its extra 32MP. Higher resolution can also make it easier to crop shots somewhat more aggressively. The more recent S1R is going to have a benefit in sensor tech.
