Olympus E-620 vs YI M1 Sensor Comparison

More often than not, it can be tough to see the contrast in sensor sizing just by looking through technical specs. The graphic underneath should provide you a greater sense of the sensor dimensions in the E-620 and M1.

As you can tell, the two cameras have the same sensor dimensions but not the same resolution. You should anticipate the YI M1 to provide you with more detail with its extra 8 Megapixels. Greater resolution will help you crop images a bit more aggressively. The older E-620 will be disadvantaged when it comes to sensor tech.
