The K-01 was unveiled 3 years later than the K20D and that is quite a significant gap as far as technology is concerned. Both of these cameras have different body design with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax K20D being a Mid-size SLR camera.

Before diving straight to a in depth comparison, here is a short highlight of how the K-01 matches up versus the K20D with regards to portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Pentax K-01 and Pentax K20D. The full galleries are viewable at Pentax K-01 Gallery and Pentax K20D Gallery.

If you're planning to lug around your camera frequently, you are going to need to factor in its weight and volume. The Pentax K-01 features outside measurements of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") having a weight of 561 grams (1.24 lbs) while the Pentax K20D has sizing of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") and a weight of 800 grams (1.76 lbs).

Take a look at the Pentax K-01 and Pentax K20D in the new Camera with Lens Size Comparison Tool.

Bear in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you have chosen during that time. Below is a front view size comparison of the K-01 compared to the K20D.

Considering dimensions and weight, the portability score of the K-01 and K20D is 76 and 59 respectively.

Quite often, it is hard to see the gap between sensor measurements simply by going over specifications. The photograph below will help offer you a stronger sense of the sensor measurements in the K-01 and K20D.

Plainly, both the cameras provide the same sensor dimensions but not the same resolution. You should expect to see the Pentax K-01 to offer you more detail having an extra 1 Megapixels. Greater resolution will also help you crop images more aggressively. The more modern K-01 will have an advantage in sensor technology.
