Sometimes, it is difficult to picture the difference between sensor sizing just by going over specifications. The photograph below should offer you a clearer sense of the sensor dimensions in the 5D MIII and E-300.

To sum up, the two cameras feature different megapixel count and different sensor sizing. The 5D MIII having a bigger sensor is going to make shooting shallower depth of field less difficult and the Canon 5D MIII will offer you greater detail having an extra 14 Megapixels. Higher resolution will also make it easier to crop pictures way more aggressively. The younger 5D MIII provides an edge with regard to sensor tech.
