As you can plainly see, the 2 cameras come with different resolutions and different sensor measurements. The GH3 due to its tinier sensor is going to make shooting bokeh trickier and the Panasonic GH3 will offer you extra detail having its extra 10 Megapixels. Higher resolution can also let you crop shots a good deal more aggressively. The younger GH3 provides an advantage with regard to sensor innovation.
