As you can tell, both of the cameras come with different resolutions and different sensor dimensions. The E-400 due to its tinier sensor is going to make shooting shallow depth of field more challenging and the Sony A7R IV will give more detail due to its extra 51 Megapixels. Greater resolution will also allow you to crop images a good deal more aggressively. The more aged E-400 is going to be disadvantaged when it comes to sensor tech.
