As you can tell, both the cameras have got different megapixels and different sensor sizing. The WG-4 having a tinier sensor is going to make achieving shallow depth of field more challenging and the Sony A7 III will offer more detail using its extra 8MP. Greater resolution can also enable you to crop pics much more aggressively. The older WG-4 is going to be behind when it comes to sensor technology.
