The K20D was revealed 7 years prior to the Q-S1 which is quite a sizable gap as far as tech is concerned. The two cameras offer different body type with the Pentax K20D being a Mid-size SLR camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.

Before we go in to a complete comparison, below is a simple view of how the K20D scores against the Q-S1 with regard to portability, imaging, features and an overall mark.

Following is a sample of the gallery pics for Pentax K20D and Pentax Q-S1. The full galleries are provided at Pentax K20D Gallery and Pentax Q-S1 Gallery.

Oftentimes, it is very hard to imagine the gap between sensor dimensions just by checking specs. The pic below should offer you a much better sense of the sensor sizes in the K20D and Q-S1.

As you can plainly see, the two cameras offer different megapixels and different sensor dimensions. The K20D using its larger sensor is going to make getting shallow depth of field simpler and the Pentax K20D will give you greater detail because of its extra 3MP. Greater resolution will also enable you to crop pics a little more aggressively. The more aged K20D is going to be disadvantaged in sensor tech.
