Usually, it's hard to visualize the difference between sensor sizing simply by going over a spec sheet. The visual here should give you a greater sense of the sensor dimensions in the GH4 and K100D.

Clearly, both cameras come with different megapixels and different sensor sizing. The GH4 due to its tinier sensor is going to make achieving bokeh more difficult and the Panasonic GH4 will deliver extra detail utilizing its extra 10 Megapixels. Higher resolution will also make it easier to crop photographs a good deal more aggressively. The fresher GH4 provides an edge in sensor tech.
