Clearly, both the cameras have got different megapixels and different sensor sizes. The LZ40 using its smaller sensor will make achieving shallower depth of field more difficult and the Sony A7R III will provide you with greater detail because of its extra 22 Megapixels. Higher resolution can also help you crop photographs much more aggressively. The more aged LZ40 will be disadvantaged when it comes to sensor innovation.
