The X-5 was manufactured 24 months after the SD1 which makes the cameras a generation away from one another. Both of these cameras come with different body type with the Pentax X-5 being a SLR-like (bridge) camera and the Sigma SD1 being a Mid-size SLR camera.

Before delving in to a thorough comparison, below is a short summary of how the X-5 scores against the SD1 with regard to portability, imaging, features and an overall mark.

Here is a preview of the gallery images for Pentax X-5 and Sigma SD1. The entire galleries are provided at Pentax X-5 Gallery and Sigma SD1 Gallery.

Sometimes, it's difficult to see the contrast in sensor dimensions simply by seeing a spec sheet. The picture here should provide you a stronger sense of the sensor sizes in the X-5 and SD1.

As you can see, both cameras posses different megapixel count and different sensor dimensions. The X-5 because of its smaller sensor will make achieving shallower DOF more difficult and the Pentax X-5 will show more detail due to its extra 1MP. Higher resolution will also enable you to crop shots somewhat more aggressively. The newer X-5 will have a benefit with regard to sensor innovation.
