Sigma DP1x vs Sony A7R Sensor Comparison

Quite often, it is tough to envision the gap between sensor sizing purely by checking specifications. The graphic below might provide you a more clear sense of the sensor measurements in the DP1x and A7R.

To sum up, the 2 cameras have different megapixel count and different sensor sizing. The DP1x because of its tinier sensor will make achieving bokeh trickier and the Sony A7R will resolve extra detail as a result of its extra 31 Megapixels. Greater resolution can also make it easier to crop pics a bit more aggressively. The older DP1x is going to be disadvantaged in sensor innovation.
