Reviewer score 90% (normalized by Neofiliac)

Reviewers from cameralabs have found:

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.

Pros

Excellent battery life
Easy to use
Bluetooth connectivity

Cons

No viewfinder blackout

Reviewers from digitaltrends have found:

The A9 has a native ISO of 100-51,200 but can be expanded down to 50 and up to 204,800. With a fast card and Sony's XAVC S high-bitrate format, you can record 4K/30p at 100Mbps. 4K video with full pixel readout is possible in both full-frame and Super35 crop modes.

Pros

Top-notch image quality
Excellent autofocus
Excellent battery life

Cons

Menu system is inscrutable
No advanced video color profiles

Reviewer score 93% (normalized by Neofiliac)

Reviewers from pcmag have found:

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.

Pros

Fantastic autofocus system
4K video
5-axis sensor stabilization
Excellent EVF

Cons

Lack of third-party lens support
