The SD1 was brought out 10 months earlier than the HX7V and they are both of a similar generation. Each of these cameras come with different body type with the Sigma SD1 being a Mid-size SLR camera and the Sony HX7V being a Compact camera.

Before getting straight into a complete comparison, below is a short introduction of how the SD1 scores versus the HX7V in relation to portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Sigma SD1 and Sony Cyber-shot DSC-HX7V. The entire galleries are viewable at Sigma SD1 Gallery and Sony HX7V Gallery.

For anyone who is intending to lug around your camera regularly, you're going to have to factor its weight and dimensions.

Normally, its difficult to picture the gap in sensor measurements just by looking through technical specs. The graphic below might give you a much better sense of the sensor measurements in the SD1 and HX7V.

As you can tell, each of these cameras have got different resolutions and different sensor measurements. The SD1 due to its bigger sensor is going to make achieving shallow DOF less difficult and the Sony HX7V will render extra detail having its extra 1 Megapixels. Higher resolution will also make it easier to crop pictures much more aggressively. The older SD1 will be behind with regard to sensor innovation.
