The K20D was released 6 years prior to the RX10 and that is quite a sizable gap as far as technology is concerned. Both cameras come with different body type with the Pentax K20D being a Mid-size SLR camera and the Sony RX10 being a SLR-like (bridge) camera.

Before getting straight into a step-by-step comparison, below is a brief view of how the K20D scores versus the RX10 when it comes to portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Pentax K20D and Sony Cyber-shot DSC-RX10. The complete galleries are available at Pentax K20D Gallery and Sony RX10 Gallery.

When you are going to carry your camera frequently, you'll have to take into account its weight and measurements.

Normally, it's tough to visualize the difference between sensor sizing only by looking at technical specs. The graphic underneath might offer you a better sense of the sensor dimensions in the K20D and RX10.

As you can tell, both cameras have got different megapixels and different sensor sizing. The K20D due to its larger sensor is going to make getting shallower DOF less difficult and the Sony RX10 will resolve greater detail as a result of its extra 5MP. Greater resolution can also enable you to crop pics much more aggressively. The older K20D is going to be disadvantaged when it comes to sensor tech.
