Pentax XG-1 vs Sigma DP2x

Let's examine more in depth at the Pentax XG-1 vs Sigma DP2x, former being a Small Sensor Superzoom while the latter is a Large Sensor Compact by competitors Pentax and Sigma. There exists a sizable gap among the resolutions of the XG-1 (16MP) and DP2x (5MP) and the XG-1 (1/2.3") and DP2x (APS-C) come with different sensor sizes.

The XG-1 was revealed 3 years later than the DP2x and that is a fairly significant difference as far as camera technology is concerned. Both of the cameras offer different body type with the Pentax XG-1 being a SLR-like (bridge) camera and the Sigma DP2x being a Large Sensor Compact camera.

Before getting straight into a more detailed comparison, below is a simple summary of how the XG-1 matches up versus the DP2x in relation to portability, imaging, features and an overall rating.

The following is a preview of the gallery photos for Pentax XG-1 & Sigma DP2x. The full galleries are provided at Pentax XG-1 Gallery & Sigma DP2x Gallery.

If you are going to carry your camera frequently, you will need to factor its weight and size. The Pentax XG-1 features physical measurements of 119mm x 89mm x 98mm (4.7" x 3.5" x 3.9") and a weight of 567 grams (1.25 lbs) whilst the Sigma DP2x has specifications of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") and a weight of 280 grams (0.62 lbs).

Don't forget, the weight of an ILC will vary based on the lens you are utilising at that time. Following is the front view sizing comparison of the XG-1 against the DP2x.

Taking into consideration dimensions and weight, the portability rating of the XG-1 and DP2x is 66 and 86 respectively.

Sometimes, it's difficult to visualize the gap in sensor sizing simply by looking through a spec sheet. The graphic here may give you a better sense of the sensor measurements in the XG-1 and DP2x.

As you can see, each of these cameras enjoy different megapixel count and different sensor sizing. The XG-1 with its smaller sensor is going to make getting bokeh more challenging and the Pentax XG-1 will provide you with more detail because of its extra 11MP. Higher resolution will also allow you to crop photographs far more aggressively. The more modern XG-1 provides an edge in sensor tech.
