Pentax K100D vs Sony RX10 III

Below, we are reviewing the Pentax K100D versus Sony RX10 III, one is a Entry-Level DSLR and the other is a Large Sensor Superzoom by companies Pentax and Sony. There exists a big gap between the sensor resolutions of the K100D (6MP) and RX10 III (20MP) and the K100D (APS-C) and RX10 III (1") feature different sensor sizes.

The K100D was introduced 10 years before the RX10 III which is quite a big gap as far as technology is concerned. Both cameras come with different body type with the Pentax K100D being a Compact SLR camera and the Sony RX10 III being a SLR-like (bridge) camera.

Before diving in to a full comparison, below is a simple introduction of how the K100D scores versus the RX10 III with regards to portability, imaging, features and an overall mark.

Here is a sample of the gallery pictures for Pentax K100D and Sony Cyber-shot DSC-RX10 III. The whole galleries are available at Pentax K100D Gallery and Sony RX10 III Gallery.

In case you're planning to travel with your camera often, you will have to consider its weight and volume. The Pentax K100D enjoys physical measurements of 129mm x 93mm x 70mm (5.1" x 3.7" x 2.8") and a weight of 660 grams (1.46 lbs) while the Sony RX10 III has sizing of 133mm x 94mm x 127mm (5.2" x 3.7" x 5.0") accompanied by a weight of 1051 grams (2.32 lbs).

Always remember, the weight of an Interchangeable Lens Camera will vary based on the lens you are utilising during that time. Below is the front view dimension comparison of the K100D compared to the RX10 III.

Taking into consideration dimensions and weight, the portability rating of the K100D and RX10 III is 64 and 53 respectively.

Sometimes, it is very difficult to imagine the gap between sensor dimensions only by looking at a spec sheet. The picture underneath should give you a clearer sense of the sensor sizing in the K100D and RX10 III.

As you can see, both of these cameras have got different megapixel count and different sensor dimensions. The K100D having a larger sensor is going to make achieving shallower depth of field simpler and the Sony RX10 III will give you more detail using its extra 14 Megapixels. Greater resolution can also enable you to crop pics much more aggressively. The more aged K100D is going to be behind when it comes to sensor innovation.
