Canon 40D vs Olympus E-300 Sensor Comparison

Quite often, it's difficult to visualise the difference in sensor sizes purely by viewing specifications. The pic here will help offer you a clearer sense of the sensor measurements in the 40D and E-300.

Plainly, both of those cameras enjoy different megapixel count and different sensor sizes. The 40D because of its bigger sensor will make shooting shallower depth of field easier and the Canon 40D will render extra detail having its extra 2MP. Higher resolution will also enable you to crop shots far more aggressively. The younger 40D is going to have an advantage in sensor technology.
