All in all, both of the cameras provide different resolutions and different sensor measurements. The E-450 using its tinier sensor will make achieving bokeh harder and the Sony A7R III will resolve extra detail using its extra 32MP. Higher resolution will also enable you to crop shots more aggressively. The older E-450 is going to be disadvantaged when it comes to sensor innovation.
