Sigma DP2s vs Sony A7S III Sensor Comparison

Usually, it is very tough to visualise the gap between sensor sizes simply by reading technical specs. The pic underneath will help give you a much better sense of the sensor dimensions in the DP2s and A7S III.

As you can tell, each of these cameras come with different resolutions and different sensor sizes. The DP2s having a tinier sensor will make shooting bokeh more difficult and the Sony A7S III will offer you more detail because of its extra 7 Megapixels. Greater resolution will also help you crop images a good deal more aggressively. The more aged DP2s is going to be disadvantaged with regard to sensor innovation.
