Pentax X70 vs Sigma DP2s

Let's look more in depth at the Pentax X70 and Sigma DP2s, one is a Small Sensor Superzoom and the latter is a Large Sensor Compact by brands Pentax and Sigma. There is a sizeable difference among the sensor resolutions of the X70 (12MP) and DP2s (5MP) and the X70 (1/2.3") and DP2s (APS-C) offer different sensor size.

The X70 was brought out 11 months earlier than the DP2s and they are of a similar generation. Each of the cameras have different body design with the Pentax X70 being a SLR-like (bridge) camera and the Sigma DP2s being a Large Sensor Compact camera.

Before delving right into a comprehensive comparison, here is a quick highlight of how the X70 grades against the DP2s in regards to portability, imaging, features and an overall score.

This is a preview of the gallery photos for Pentax X70 and Sigma DP2s. The entire galleries are viewable at Pentax X70 Gallery and Sigma DP2s Gallery.

For anyone who is aiming to carry around your camera, you have to take into account its weight and volume. The Pentax X70 comes with outside measurements of 110mm x 83mm x 90mm (4.3" x 3.3" x 3.5") having a weight of 410 grams (0.90 lbs) while the Sigma DP2s has sizing of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") having a weight of 280 grams (0.62 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you have during that time. The following is a front view size comparison of the X70 versus the DP2s.

Looking at size and weight, the portability grade of the X70 and DP2s is 71 and 86 respectively.

Often, it is very hard to imagine the difference in sensor sizes simply by looking through a spec sheet. The image below might give you a clearer sense of the sensor measurements in the X70 and DP2s.

Clearly, both the cameras have different resolutions and different sensor sizes. The X70 because of its smaller sensor is going to make achieving bokeh tougher and the Pentax X70 will result in greater detail having its extra 7 Megapixels. Higher resolution will allow you to crop pictures a bit more aggressively. The more aged X70 will be disadvantaged in sensor innovation.
