The K100D was introduced 9 years earlier than the RX1R II and that is a fairly significant difference as far as camera tech is concerned. Each of these cameras have different body design with the Pentax K100D being a Compact SLR camera and the Sony RX1R II being a Large Sensor Compact camera.

Before we go straight to a comprehensive comparison, here is a short introduction of how the K100D grades versus the RX1R II in the way of portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Pentax K100D & Sony Cyber-shot DSC-RX1R II. The whole galleries are provided at Pentax K100D Gallery & Sony RX1R II Gallery.

Usually, it's hard to picture the contrast in sensor measurements only by viewing a spec sheet. The graphic underneath will help offer you a greater sense of the sensor measurements in the K100D and RX1R II.

Clearly, the 2 cameras provide different megapixels and different sensor measurements. The K100D using its smaller sensor is going to make achieving bokeh more challenging and the Sony RX1R II will render extra detail using its extra 36MP. Higher resolution can also make it easier to crop shots more aggressively. The older K100D will be disadvantaged in sensor innovation.
