Epson R-D1x vs Sony a1 Sensor Comparison

Often, it is very hard to picture the gap between sensor dimensions only by looking at specifications. The picture here may give you a more clear sense of the sensor sizing in the R-D1x and a1.

To sum up, each of these cameras feature different megapixel count and different sensor dimensions. The R-D1x due to its tinier sensor is going to make getting shallower DOF more difficult and the Sony a1 will give more detail having its extra 44MP. Higher resolution can also help you crop photographs way more aggressively. The more aged R-D1x is going to be disadvantaged in sensor innovation.
