As you can tell, both of those cameras provide different resolutions and different sensor sizes. The GH5S featuring a tinier sensor will make shooting shallower depth of field more challenging and the Pentax K-x will give greater detail as a result of its extra 2 Megapixels. Greater resolution will allow you to crop images more aggressively. The more recent GH5S is going to have a benefit in sensor innovation.
