Sigma DP1 vs Sony RX1

Lets look more in depth at the Sigma DP1 and Sony RX1, both Large Sensor Compact cameras by rivals Sigma and Sony. There exists a huge gap among the image resolutions of the DP1 (5MP) and RX1 (24MP) and the DP1 (APS-C) and RX1 (Full frame) provide different sensor measurements.

The DP1 was revealed 5 years earlier than the RX1 which is a fairly significant gap as far as camera technology is concerned. Both the cameras have the same body design (Large Sensor Compact).

Before diving straight to a more detailed comparison, here is a short view of how the DP1 grades versus the RX1 in regards to portability, imaging, features and an overall mark.

Below is a sample of the gallery pictures for Sigma DP1 and Sony Cyber-shot DSC-RX1. The full galleries are available at Sigma DP1 Gallery and Sony RX1 Gallery.

If you're looking to travel with your camera often, you should consider its weight and dimensions. The Sigma DP1 offers outer measurements of 113mm x 60mm x 50mm (4.4" x 2.4" x 2.0") having a weight of 270 grams (0.60 lbs) whilst the Sony RX1 has dimensions of 113mm x 65mm x 70mm (4.4" x 2.6" x 2.8") having a weight of 482 grams (1.06 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you are using at that time. Here is a front view scale comparison of the DP1 against the RX1.

Using dimensions and weight, the portability rating of the DP1 and RX1 is 87 and 79 respectively.

Normally, it is tough to picture the gap in sensor dimensions just by seeing specs. The pic below will help provide you a clearer sense of the sensor measurements in the DP1 and RX1.

As you can plainly see, each of the cameras provide different resolutions and different sensor dimensions. The DP1 using its smaller sensor is going to make getting shallow depth of field harder and the Sony RX1 will produce more detail because of its extra 19MP. Greater resolution can also let you crop pics more aggressively. The more aged DP1 will be disadvantaged when it comes to sensor technology.
