Olympus E-PM2 vs YI M1 Sensor Comparison

Often, its difficult to envision the contrast in sensor measurements simply by viewing specifications. The photograph here might give you a stronger sense of the sensor sizes in the E-PM2 and M1.

Plainly, the 2 cameras posses the exact same sensor measurements but not the same resolution. You can expect to see the YI M1 to result in more detail because of its extra 4 Megapixels. Greater resolution can also make it easier to crop pics somewhat more aggressively. The older E-PM2 will be behind when it comes to sensor innovation.
