More often than not, it is hard to visualise the gap in sensor measurements only by viewing specifications. The graphic below will help offer you a far better sense of the sensor measurements in the A7 III and A7 IV.

Plainly, both of those cameras come with the identical sensor size albeit not the same resolution. You can expect the Sony A7 IV to result in extra detail having an extra 9 Megapixels. Higher resolution will allow you to crop shots a good deal more aggressively. The older A7 III will be disadvantaged with regard to sensor innovation.
