Sigma DP2x vs Sony a5100

On this page, we are evaluating the Sigma DP2x and Sony a5100, former being a Large Sensor Compact while the other is a Entry-Level Mirrorless by companies Sigma and Sony. There exists a sizable gap between the resolutions of the DP2x (5MP) and a5100 (24MP) but both cameras offer the same sensor sizes (APS-C).

The DP2x was manufactured 4 years earlier than the a5100 and that is quite a significant difference as far as technology is concerned. Both cameras have different body design with the Sigma DP2x being a Large Sensor Compact camera and the Sony a5100 being a Rangefinder-style mirrorless camera.

Before we go right into a in depth comparison, here is a short overview of how the DP2x matches up versus the a5100 when considering portability, imaging, features and an overall grade.

If you're planning to lug around your camera, you need to consider its weight and measurements. The Sigma DP2x comes with exterior measurements of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") having a weight of 280 grams (0.62 lbs) while the Sony a5100 has proportions of 110mm x 63mm x 36mm (4.3" x 2.5" x 1.4") along with a weight of 283 grams (0.62 lbs).

Remember, the weight of an ILC will change based on the lens you have attached at the time. Here is a front view physical size comparison of the DP2x versus the a5100.

Considering dimensions and weight, the portability rating of the DP2x and a5100 is 86 and 89 respectively.

Normally, it is very difficult to visualize the gap between sensor measurements only by reading through a spec sheet. The graphic underneath should give you a more clear sense of the sensor sizing in the DP2x and a5100.

Clearly, both of the cameras have the same sensor dimensions but different resolution. You can expect to see the Sony a5100 to give extra detail due to its extra 19MP. Greater resolution will help you crop images a bit more aggressively. The older DP2x is going to be disadvantaged in sensor innovation.
