Sigma DP2 vs Sony a1 Sensor Comparison

Generally, it is very tough to visualise the contrast between sensor sizing purely by reading specs. The visual below should offer you a clearer sense of the sensor measurements in the DP2 and a1.

All in all, both of the cameras posses different megapixel count and different sensor sizing. The DP2 featuring a tinier sensor will make achieving bokeh tougher and the Sony a1 will offer greater detail due to its extra 45 Megapixels. Higher resolution can also make it easier to crop pictures somewhat more aggressively. The older DP2 is going to be disadvantaged with regard to sensor technology.
