Leica Q3 vs Sigma DP2 Sensor Comparison

More often than not, its tough to envision the gap between sensor sizing only by reading through specs. The visual here may give you a greater sense of the sensor sizes in the Q3 and DP2.

All in all, both of those cameras have different resolutions and different sensor sizing. The Q3 using its bigger sensor will make shooting bokeh easier and the Leica Q3 will resolve greater detail having an extra 55 Megapixels. Higher resolution can also help you crop shots a bit more aggressively. The younger Q3 is going to have an edge when it comes to sensor tech.
