Panasonic GH3 vs Sony A7c Sensor Comparison

Normally, its difficult to imagine the contrast in sensor dimensions only by researching specifications. The pic here should offer you a more clear sense of the sensor dimensions in the GH3 and A7c.

To sum up, each of these cameras offer different megapixels and different sensor dimensions. The GH3 with its smaller sensor is going to make achieving shallow depth of field harder and the Sony A7c will provide you with greater detail using its extra 8MP. Greater resolution will also help you crop photos a little more aggressively. The more aged GH3 will be disadvantaged in sensor technology.
