Olympus E-P3 vs Sony A7c Sensor Comparison

As you can plainly see, both of the cameras have got different megapixels and different sensor measurements. The E-P3 due to its tinier sensor is going to make achieving bokeh more challenging and the Sony A7c will offer you greater detail due to its extra 12 Megapixels. Higher resolution will make it easier to crop shots much more aggressively. The older E-P3 is going to be behind when it comes to sensor innovation.
