Sony RX10 vs Sony A77 Sensor Comparison

More often than not, its hard to visualize the difference in sensor measurements purely by checking out a spec sheet. The graphic underneath will help offer you a better sense of the sensor sizing in the RX10 and A77.

Clearly, each of the cameras offer different megapixels and different sensor measurements. The RX10 using its smaller sensor is going to make shooting shallow DOF trickier and the Sony A77 will provide more detail because of its extra 4 Megapixels. Greater resolution can also allow you to crop images a little more aggressively. The fresher RX10 should have an advantage in sensor technology.
