Olympus TG-820 iHS vs Sony A7 III Sensor Comparison

As you can tell, the 2 cameras have got different resolutions and different sensor sizing. The TG-820 iHS using its tinier sensor will make getting shallow depth of field trickier and the Sony A7 III will give more detail because of its extra 12 Megapixels. Greater resolution will let you crop photos much more aggressively. The older TG-820 iHS is going to be disadvantaged with regard to sensor technology.
