The DP1x was introduced 15 months prior to the A580 making the cameras a generation away from one another. Both the cameras offer different body type with the Sigma DP1x being a Large Sensor Compact camera and the Sony A580 being a Compact SLR camera.

Before we go in to a more detailed comparison, below is a short highlight of how the DP1x scores vs the A580 with respect to portability, imaging, features and an overall score.

The following is a sample of the gallery pictures for Sigma DP1x and Sony Alpha DSLR-A580. The whole galleries are viewable at Sigma DP1x Gallery and Sony A580 Gallery.

If you're planning to carry around your camera often, you will want to factor in its weight and dimensions.

Typically, it can be tough to see the gap in sensor sizes simply by going through a spec sheet. The picture here will help offer you a much better sense of the sensor measurements in the DP1x and A580.

Clearly, the two cameras enjoy the same exact sensor sizing but not the same megapixels. You should anticipate the Sony A580 to produce more detail using its extra 11MP. Greater resolution will allow you to crop photos far more aggressively. The more aged DP1x will be disadvantaged in sensor technology.
