There is no question the Sony a7 III just announced by Sony is making a splash in the midrange to professional camera markets. We have a $1,998.00 USD Full Frame camera that can shoot 10fps at the full 24MP sensor resolution with probably the best AF tracking system ever shipped on a camera aside from the slightly better Sony a9. The low light performance of the new a7 III is quite frankly impressive with nearly as clean video to the king of low light the a7s II up until ISO 12,800.
It also has the same high-quality 120fps Full HD mode in both full frame downsampling and APS-C crop modes with continuous reliable AF tracking that performs as good as the a9 system because when it comes to spec comparisons they seem identical. You will be better off with this camera if you are looking for 120fps full HD than any we have seen before as quality, low noise, focus tracking and dynamic range all come together to create a superb package.
