To sum up, the 2 cameras provide different resolutions and different sensor sizing. The G10 having a tinier sensor will make getting bokeh more challenging and the Sony A7R III will offer more detail having an extra 30 Megapixels. Higher resolution can also help you crop shots more aggressively. The older G10 is going to be disadvantaged in sensor innovation.
