Pentax K20D vs Pentax RZ10

Here, we will be comparing the Pentax K20D versus Pentax RZ10, former being a Advanced DSLR while the latter is a Small Sensor Compact and both of them are produced by Pentax. The sensor resolution of the K20D (15MP) and the RZ10 (14MP) is pretty comparable but the K20D (APS-C) and RZ10 (1/2.3") provide totally different sensor dimensions.

The K20D was brought out 4 years prior to the RZ10 and that is a fairly significant difference as far as camera technology is concerned. Both the cameras feature different body design with the Pentax K20D being a Mid-size SLR camera and the Pentax RZ10 being a Compact camera.

Before getting into a full comparison, here is a short overview of how the K20D matches up against the RZ10 in regards to portability, imaging, features and an overall rating.

Below is a preview of the gallery images for Pentax K20D & Pentax Optio RZ10. The entire galleries are viewable at Pentax K20D Gallery & Pentax RZ10 Gallery.

If you're planning to carry your camera regularly, you are going to need to factor in its weight and size. The Pentax K20D provides physical dimensions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") along with a weight of 800 grams (1.76 lbs) and the Pentax RZ10 has specifications of 97mm x 61mm x 33mm (3.8" x 2.4" x 1.3") having a weight of 178 grams (0.39 lbs).

Do not forget, the weight of an ILC will change depending on the lens you are using during that time. Following is a front view measurements comparison of the K20D against the RZ10.

Taking into account dimensions and weight, the portability rating of the K20D and RZ10 is 59 and 92 respectively.

Quite often, it is very difficult to see the gap in sensor sizing only by going through a spec sheet. The graphic below should give you a greater sense of the sensor dimensions in the K20D and RZ10.

Clearly, each of the cameras come with different megapixel count and different sensor sizing. The K20D because of its bigger sensor will make achieving bokeh less difficult and the Pentax K20D will produce greater detail having its extra 1 Megapixels. Higher resolution will also enable you to crop pictures a good deal more aggressively. The older K20D will be disadvantaged when it comes to sensor innovation.
