The GH3 was introduced 7 years before the fp which is a fairly big difference as far as camera technology is concerned. Both the cameras offer different body type with the Panasonic GH3 being a SLR-style mirrorless camera and the Sigma fp being a Rangefinder-style mirrorless camera.

Before getting through a in-depth comparison, below is a brief summation of how the GH3 grades against the fp with respect to portability, imaging, features and an overall score.

If you are going to carry around your camera regularly, you have to take into account its weight and dimensions.

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.
