To sum up, the two cameras posses different megapixel count and different sensor measurements. The GM1 using its smaller sensor is going to make achieving shallow depth of field harder and the Sony A6400 will result in more detail because of its extra 8MP. Greater resolution will also allow you to crop photos somewhat more aggressively. The older GM1 will be disadvantaged when it comes to sensor technology.
