Olympus E-M1 III vs Sony A7 III
Olympus E-M1 III was introduced to market in February 2020 and Sony A7 III was launched in February 2018. There is 23 months difference between E-M1 III and A7 III so we don't expect to see a huge technology difference between these two cameras but it would still give an advantage to younger E-M1 III, especially in sensor tech.
