On February 26, 2018 Sony announced the third generation of the A7 camera line – Sony A7 III. The original A7 was the first Sony mirorrless camera, released back in 2013. It was amazing how a full frame camera can be squeezed in such small body, but the camera had some major lay-downs. It was slow and not very responsive. An year later, in November, 2014 Sony released the second generation of A7 camera line. It was improvement over A7 but incremental, without any big updates.
Specifications
The new Sony A7 III is a huge step ahead. It is not only upgrade to the previous generation model but it is a mini copy of the flagship A9. It has almost the same auto-focus system as A9, it has the same Z battery, joystick, dual card slots, etc. A7 III is equipped with new designed 24Mpx BSI (Backside Illuminated) sensor, 4k video without pixel binning, IBIS (In Body Image Stabilization).
