As you can see, both of the cameras come with different megapixels and different sensor measurements. The R7 because of its tinier sensor is going to make achieving shallower depth of field more difficult and the Canon R7 will offer greater detail as a result of its extra 9 Megapixels. Greater resolution will allow you to crop photos a good deal more aggressively. The newer R7 provides an advantage with regard to sensor technology.
