Panasonic GX8 vs Sigma fp Sensor Comparison

Sometimes, it's tough to visualize the gap in sensor measurements simply by going through specifications. The photograph underneath will help offer you a better sense of the sensor measurements in the GX8 and fp.

To sum up, both the cameras posses different megapixels and different sensor measurements. The GX8 because of its smaller sensor is going to make shooting shallower depth of field trickier and the Sigma fp will produce extra detail due to its extra 5 Megapixels. Greater resolution will also help you crop images somewhat more aggressively. The older GX8 will be disadvantaged with regard to sensor technology.
