The DP1s was revealed 8 years earlier than the A9 and that is a fairly big gap as far as camera tech is concerned. Each of the cameras feature different body design with the Sigma DP1s being a Large Sensor Compact camera and the Sony A9 being a SLR-style mirrorless camera.

Before delving straight to a step-by-step comparison, here is a short highlight of how the DP1s scores vs the A9 when considering portability, imaging, features and an overall grade.

Generally, it is hard to visualise the gap in sensor measurements simply by researching specifications. The visual here will help offer you a more clear sense of the sensor dimensions in the DP1s and A9.

Plainly, both of the cameras come with different resolutions and different sensor measurements. The DP1s using its smaller sensor will make shooting shallower DOF harder and the Sony A9 will result in extra detail because of its extra 19 Megapixels. Greater resolution will also let you crop photos a good deal more aggressively. The older DP1s will be disadvantaged with regard to sensor tech.
