The DP1s was announced 5 years prior to the A7S and that is a fairly significant difference as far as camera technology is concerned. Each of the cameras offer different body type with the Sigma DP1s being a Large Sensor Compact camera and the Sony A7S being a SLR-style mirrorless camera.

Before delving through a thorough comparison, below is a short view of how the DP1s matches up versus the A7S in regards to portability, imaging, features and an overall grade.

Using dimensions and weight, the portability grade of the DP1s and A7S is 90 and 77 respectively.

Sometimes, its hard to envision the gap in sensor measurements simply by researching technical specs. The photograph underneath may offer you a clearer sense of the sensor sizes in the DP1s and A7S.

As you have seen, both of those cameras enjoy different megapixels and different sensor measurements. The DP1s using its smaller sensor will make shooting shallow depth of field tougher and the Sony A7S will result in extra detail with its extra 7 Megapixels. Higher resolution will also let you crop pictures far more aggressively. The older DP1s will be behind with regard to sensor innovation.
