Olympus E-P1 vs YI M1 Sensor Comparison

Quite often, it's hard to picture the gap between sensor sizing simply by reading through technical specs. The visual underneath should offer you a clearer sense of the sensor dimensions in the E-P1 and M1.

As you have seen, both cameras posses the exact same sensor measurements albeit different MP. You can expect the YI M1 to give you more detail as a result of its extra 8 Megapixels. Higher resolution will enable you to crop pictures somewhat more aggressively. The older E-P1 is going to be disadvantaged when it comes to sensor tech.
