Pentax K-S1 vs Sony HX20V

The following is a extensive assessment of the Pentax K-S1 versus Sony HX20V, one is a Advanced DSLR and the other is a Small Sensor Superzoom by competitors Pentax and Sony. The sensor resolution of the K-S1 (20MP) and the HX20V (18MP) is fairly well matched but the K-S1 (APS-C) and HX20V (1/2.3") use different sensor sizing.

The K-S1 was introduced 2 years after the HX20V which is quite a serious gap as far as tech is concerned. Both the cameras offer different body type with the Pentax K-S1 being a Mid-size SLR camera and the Sony HX20V being a Compact camera.

Before going in to a in-depth comparison, below is a short overview of how the K-S1 matches up versus the HX20V when considering portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Pentax K-S1 and Sony Cyber-shot DSC-HX20V. The whole galleries are viewable at Pentax K-S1 Gallery and Sony HX20V Gallery.

For anybody who is going to travel with your camera frequently, you'll need to consider its weight and volume. The Pentax K-S1 features outer measurements of 121mm x 93mm x 70mm (4.8" x 3.7" x 2.8") along with a weight of 558 grams (1.23 lbs) while the Sony HX20V has sizing of 107mm x 62mm x 35mm (4.2" x 2.4" x 1.4") with a weight of 254 grams (0.56 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you have chosen at the time. Underneath is the front view dimensions comparison of the K-S1 and the HX20V.

Factoring in size and weight, the portability rating of the K-S1 and HX20V is 69 and 90 respectively.

Often, it can be tough to imagine the gap between sensor dimensions purely by reading through specs. The image below will help offer you a far better sense of the sensor sizing in the K-S1 and HX20V.

All in all, both of the cameras enjoy different resolutions and different sensor dimensions. The K-S1 having a larger sensor is going to make getting shallower DOF less difficult and the Pentax K-S1 will give you more detail using its extra 2MP. Greater resolution will allow you to crop pics far more aggressively. The fresher K-S1 should have an advantage when it comes to sensor tech.
