Panasonic GM1 vs Sony a5100 Sensor Comparison
Typically, it is hard to see the contrast between sensor sizes only by checking specifications. The pic underneath may give you a stronger sense of the sensor measurements in the GM1 and a5100.
Plainly, the 2 cameras provide different resolutions and different sensor sizes. The GM1 due to its tinier sensor will make achieving shallow depth of field more difficult and the Sony a5100 will give more detail as a result of its extra 8 Megapixels. Greater resolution will also let you crop images more aggressively. The more aged GM1 is going to be disadvantaged with regard to sensor technology.
