More often than not, it is very hard to picture the gap between sensor sizes just by checking technical specs. The pic below will provide you a much better sense of the sensor sizing in the SX420 IS and A7R.

As you have seen, each of these cameras enjoy different resolutions and different sensor sizes. The SX420 IS featuring a tinier sensor is going to make shooting shallow depth of field more challenging and the Sony A7R will resolve more detail having its extra 16MP. Greater resolution will also help you crop photos far more aggressively. The younger SX420 IS should have an advantage when it comes to sensor tech.
