Typically, it can be hard to picture the difference in sensor dimensions purely by researching specs. The pic below will offer you a better sense of the sensor sizing in the 1s and A7 III.

As you can plainly see, the two cameras posses different resolutions and different sensor dimensions. The 1s having a smaller sensor is going to make shooting shallow depth of field tougher and the Sony A7 III will render greater detail having an extra 12MP. Greater resolution will enable you to crop photos somewhat more aggressively. The more aged 1s will be disadvantaged with regard to sensor technology.
