As you can tell, the two cameras posses different megapixel count and different sensor measurements. The K-30 having a smaller sensor is going to make achieving shallow DOF tougher and the Sony A7R IV will show greater detail having an extra 45 Megapixels. Greater resolution will enable you to crop images somewhat more aggressively. The older K-30 will be disadvantaged with regard to sensor innovation.
