The K-01 was introduced 3 years before the K-S2 which is a fairly sizable gap as far as camera technology is concerned. Each of these cameras have different body design with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax K-S2 being a Compact SLR camera.

Before getting right into a comprehensive comparison, here is a simple highlight of how the K-01 scores versus the K-S2 in terms of portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Pentax K-01 and Pentax K-S2. The whole galleries are provided at Pentax K-01 Gallery and Pentax K-S2 Gallery.

Keep in mind, the weight of an Interchangeable Lens Camera will change depending on the lens you are working with during that time. Here is a front view sizing comparison of the K-01 compared to the K-S2.

Factoring in dimensions and weight, the portability rating of the K-01 and K-S2 is 76 and 64 respectively.

Sometimes, it is very tough to visualise the gap in sensor dimensions only by researching technical specs. The pic below might give you a greater sense of the sensor sizing in the K-01 and K-S2.

As you have seen, both the cameras provide the same sensor dimensions but not the same megapixels. You should anticipate the Pentax K-S2 to result in extra detail using its extra 4 Megapixels. Greater resolution can also enable you to crop pics more aggressively. The more aged K-01 will be behind with regard to sensor innovation.
