Sigma DP1x vs Sony RX100

Let's look a little more in depth at the Sigma DP1x versus Sony RX100, both Large Sensor Compact cameras by companies Sigma and Sony. There exists a huge gap among the resolutions of the DP1x (5MP) and RX100 (20MP) and the DP1x (APS-C) and RX100 (1") boast totally different sensor sizing.

The DP1x was introduced 3 years before the RX100 and that is a fairly significant gap as far as camera technology is concerned. The two cameras have the same body design (Large Sensor Compact).

Before diving straight to a more detailed comparison, here is a quick overview of how the DP1x matches up vs the RX100 for portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Sigma DP1x and Sony Cyber-shot DSC-RX100. The whole galleries are provided at Sigma DP1x Gallery and Sony RX100 Gallery.

If you are going to lug around your camera regularly, you have to consider its weight and measurements. The Sigma DP1x enjoys external dimensions of 113mm x 60mm x 50mm (4.4" x 2.4" x 2.0") accompanied by a weight of 250 grams (0.55 lbs) whilst the Sony RX100 has proportions of 102mm x 58mm x 36mm (4.0" x 2.3" x 1.4") along with a weight of 240 grams (0.53 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you are utilising at that moment. Below is a front view sizing comparison of the DP1x against the RX100.

Using dimensions and weight, the portability rating of the DP1x and RX100 is 88 and 91 respectively.

Quite often, it's tough to envision the difference in sensor measurements simply by viewing technical specs. The visual here might provide you a much better sense of the sensor dimensions in the DP1x and RX100.

As you have seen, both of the cameras have different megapixel count and different sensor measurements. The DP1x using its larger sensor will make shooting shallow DOF less difficult and the Sony RX100 will provide you with more detail using its extra 15MP. Greater resolution can also enable you to crop photos a bit more aggressively. The older DP1x will be behind when it comes to sensor tech.
