In 2014 I selected the original A7s as one of my favourite cameras of 2014, not just for its stunning low-light capabilities for both stills and video but also because at the time, it felt like the most mature A7 model. The thing about Sony, however, is that it has become harder and harder to pick a favourite given all the new cameras constantly flooding the market. I mean, what other company has managed to release 7 full-frame cameras in less than two years?
