The DP1 was brought out 13 years earlier than the a1 which is a fairly sizable gap as far as camera tech is concerned. Both of these cameras offer different body type with the Sigma DP1 being a Large Sensor Compact camera and the Sony a1 being a SLR-style mirrorless camera.

Before delving straight into a in-depth comparison, below is a brief highlight of how the DP1 scores versus the a1 in the way of portability, imaging, features and an overall score.

Often, it is hard to see the difference in sensor sizes only by looking through a spec sheet. The image here might give you a far better sense of the sensor dimensions in the DP1 and a1.

Clearly, both of those cameras offer different megapixel count and different sensor sizes. The DP1 due to its smaller sensor will make shooting shallow DOF harder and the Sony a1 will result in more detail having its extra 45MP. Greater resolution can also let you crop images a little more aggressively. The more aged DP1 will be behind with regard to sensor innovation.
