Clearly, both of these cameras feature different resolutions and different sensor measurements. The GH4 because of its tinier sensor will make getting shallower DOF trickier and the Panasonic GH4 will give extra detail due to its extra 4MP. Greater resolution can also make it easier to crop pics way more aggressively. The older GH4 is going to be disadvantaged when it comes to sensor tech.
