Normally, it can be difficult to visualize the difference between sensor sizing merely by checking technical specs. The photograph here might give you a far better sense of the sensor sizes in the RZ18 and A7 II.

As you have seen, both of the cameras feature different megapixel count and different sensor sizing. The RZ18 with its tinier sensor is going to make achieving bokeh trickier and the Sony A7 II will give greater detail with its extra 8 Megapixels. Higher resolution will make it easier to crop pictures way more aggressively. The older RZ18 is going to be behind with regard to sensor innovation.
