Pentax XG-1 vs Sigma DP1x

Lets look a bit more closely at the Pentax XG-1 versus Sigma DP1x, one being a Small Sensor Superzoom and the latter is a Large Sensor Compact by companies Pentax and Sigma. There exists a big gap between the image resolutions of the XG-1 (16MP) and DP1x (5MP) and the XG-1 (1/2.3") and DP1x (APS-C) have totally different sensor sizing.

The XG-1 was manufactured 4 years later than the DP1x and that is quite a big gap as far as technology is concerned. Both the cameras have different body design with the Pentax XG-1 being a SLR-like (bridge) camera and the Sigma DP1x being a Large Sensor Compact camera.

Before getting straight to a step-by-step comparison, here is a concise highlight of how the XG-1 matches up vs the DP1x when it comes to portability, imaging, features and an overall rating.

Below is a preview of the gallery photos for Pentax XG-1 and Sigma DP1x. The entire galleries are viewable at Pentax XG-1 Gallery and Sigma DP1x Gallery.

If you're intending to carry your camera frequently, you'll need to factor in its weight and proportions. The Pentax XG-1 provides exterior measurements of 119mm x 89mm x 98mm (4.7" x 3.5" x 3.9") accompanied by a weight of 567 grams (1.25 lbs) whilst the Sigma DP1x has measurements of 113mm x 60mm x 50mm (4.4" x 2.4" x 2.0") having a weight of 250 grams (0.55 lbs).

Remember, the weight of an Interchangeable Lens Camera will change based on the lens you have attached at the time. Following is a front view dimension comparison of the XG-1 vs the DP1x.

Considering dimensions and weight, the portability score of the XG-1 and DP1x is 66 and 88 respectively.

Typically, its difficult to envision the gap between sensor sizing just by going over specifications. The graphic underneath may provide you a stronger sense of the sensor sizing in the XG-1 and DP1x.

Plainly, the 2 cameras provide different megapixels and different sensor sizing. The XG-1 featuring a tinier sensor will make achieving shallower DOF more challenging and the Pentax XG-1 will offer greater detail due to its extra 11MP. Higher resolution will also make it easier to crop photographs more aggressively. The younger XG-1 is going to have an edge when it comes to sensor technology.
