Normally, it is hard to picture the gap between sensor sizing merely by checking technical specs. The visual below may give you a much better sense of the sensor sizing in the 170 IS and A7S III.

As you can tell, the two cameras have got different resolutions and different sensor sizing. The 170 IS featuring a tinier sensor is going to make shooting shallower DOF trickier and the Canon 170 IS will give you extra detail due to its extra 8MP. Greater resolution will also make it easier to crop images much more aggressively. The older 170 IS is going to be disadvantaged when it comes to sensor technology.
