The Sony A7c and A7S III are two Mirrorless cameras that we will be comparing in this article. The Sony Alpha A7c is a camera in the Advanced Mirrorless class, whereas the Sony Alpha A7S III is a camera in the Pro Mirrorless class.

The Sony A7c was released in September 2020, while the Sony A7S III was released in July 2020, according to the company. Because the age gap between A7c and A7S III is just 2 months, we anticipate that this will be a fair comparison in terms of both age and technological level.
