Sigma DP1s vs Sony A7S Sensor Comparison

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.
