Pentax 645Z vs Sony HX10V Sensor Comparison

Normally, it is tough to visualize the contrast in sensor sizes purely by viewing a spec sheet. The image here may offer you a stronger sense of the sensor sizes in the 645Z and HX10V.

Clearly, both the cameras provide different megapixel count and different sensor sizes. The 645Z having a larger sensor is going to make getting shallower depth of field less difficult and the Pentax 645Z will provide you with greater detail using its extra 33MP. Greater resolution will help you crop photos more aggressively. The more modern 645Z should have an edge in sensor tech.
