Sony RX10 III vs Sony A77 II Sensor Comparison

More often than not, it is very tough to picture the gap between sensor dimensions just by looking at a spec sheet. The pic underneath will help provide you a better sense of the sensor dimensions in the RX10 III and A77 II.

Clearly, both the cameras enjoy different megapixel count and different sensor dimensions. The RX10 III featuring a tinier sensor is going to make getting shallower DOF trickier and the Sony A77 II will resolve greater detail having its extra 4 Megapixels. Higher resolution will also allow you to crop pictures far more aggressively. The newer RX10 III should have a benefit in sensor innovation.
