Reviewer score 90%The A9 is Sony’s first mirrorless full-framer to gain Bluetooth connectivity. It inherits the seamless location-embedding capabilities first-seen on the A6500. You no longer need to sign into PlayMemories and update the remote control app within the camera itself to unlock all of the manual control. Sony has also neatly resolved issues with duplicate or confusing menus.

Reviewer score 93%The Sony a9 is a big step forward for mirrorless technology. It betters the fastest, most expensive SLRs in capture rate. It also spreads its autofocus system across almost the entirety of a full-fame image sensor. The camera's ability to nab strong images in low light is further aided by its 5-axis sensor stabilization.
