The A3000 was introduced 5 years earlier than the A7 III which is quite a significant gap as far as tech is concerned. The two cameras feature the same body design (SLR-style mirrorless).

Before going into a complete comparison, here is a quick view of how the A3000 scores against the A7 III in the way of portability, imaging, features and an overall score.

Oftentimes, it is very hard to imagine the gap between sensor sizes simply by reviewing specifications. The pic below might offer you a clearer sense of the sensor sizing in the A3000 and A7 III.

To sum up, the 2 cameras come with different megapixels and different sensor sizes. The A3000 with its tinier sensor is going to make getting shallower DOF harder and the Sony A7 III will offer more detail using its extra 4 Megapixels. Greater resolution can also help you crop photos a good deal more aggressively. The more aged A3000 is going to be disadvantaged in sensor innovation.
