The K20D was released 6 years prior to the QX100 which is a fairly large difference as far as camera tech is concerned. Both of these cameras have different body design with the Pentax K20D being a Mid-size SLR camera and the Sony QX100 being a Lens-style camera.

Before we go right into a more detailed comparison, here is a brief synopsis of how the K20D matches up vs the QX100 when considering portability, imaging, features and an overall score.

Below is a sample of the gallery pics for Pentax K20D & Sony Cyber-shot DSC-QX100. The complete galleries are available at Pentax K20D Gallery & Sony QX100 Gallery.

If you are going to carry around your camera often, you should consider its weight and dimensions.

Oftentimes, its difficult to imagine the difference in sensor sizes only by viewing specifications. The pic below will offer you a clearer sense of the sensor measurements in the K20D and QX100.

To sum up, both of these cameras provide different resolutions and different sensor sizes. The K20D due to its larger sensor is going to make getting shallow DOF easier and the Sony QX100 will render extra detail as a result of its extra 5MP. Greater resolution can also enable you to crop photos more aggressively. The more aged K20D will be disadvantaged in sensor technology.
