Panasonic GH3 vs Sigma fp Sensor Comparison
Normally, it can be difficult to visualise the difference in sensor sizes purely by viewing a spec sheet. The pic here should offer you a more clear sense of the sensor dimensions in the GH3 and fp.
Clearly, the 2 cameras offer different megapixel count and different sensor sizes. The GH3 having a smaller sensor will make shooting shallow DOF harder and the Sigma fp will provide you with greater detail using its extra 9MP. Greater resolution will also allow you to crop pics a little more aggressively. The more aged GH3 will be disadvantaged with regard to sensor technology.
