Plainly, the 2 cameras come with different megapixels and different sensor dimensions. The FS42 due to its smaller sensor will make getting shallow depth of field trickier and the Sony RX100 IV will render more detail having its extra 10MP. Greater resolution can also help you crop pics a good deal more aggressively. The more aged FS42 will be disadvantaged with regard to sensor technology.
