Olympus E-P3 vs Panasonic G100 Sensor Comparison

Sometimes, its tough to visualise the gap between sensor sizing just by checking a spec sheet. The photograph here will help offer you a more clear sense of the sensor sizing in the E-P3 and G100.

Clearly, each of these cameras offer the same exact sensor sizing albeit not the same resolution. You should count on the Panasonic G100 to resolve more detail using its extra 8MP. Higher resolution can also help you crop shots a little more aggressively. The older E-P3 is going to be disadvantaged when it comes to sensor tech.
