Generally, it is difficult to picture the gap in sensor sizing merely by seeing specifications. The photograph underneath will help provide you a far better sense of the sensor measurements in the GH1 and A7R.

To sum up, both of these cameras have different megapixel count and different sensor sizing. The GH1 because of its smaller sensor is going to make achieving shallower depth of field more challenging and the Sony A7R will produce extra detail as a result of its extra 24MP. Greater resolution will let you crop pics a bit more aggressively. The older GH1 will be disadvantaged when it comes to sensor innovation.
