Sony Alpha A6400 Mirrorless Camera (Body Only)

 About Sony A6400

The α6400 introduces an advanced ‘Real-time Eye AF’, the latest version of Sony’s acclaimed Eye AF technology. This exciting new capability employs artificial intelligence-based object recognition to detect and process eye data in real time, resulting in improved accuracy, speed and tracking performance of Eye AF. In all autofocus modes, the camera now automatically detects the eyes of the subject and activates Eye AF with a half press of the shutter button, and when in AF-C or AF-A mode, the preferred eye (left or right) of your subject can be selected as the focus point. Choices include Auto / Right Eye / Left Eye, and a Switch Right / Left Eye function can be assigned to a custom function as well. This exciting new technology completely frees the photographer to focus solely on composition with full trust that focus will be tack sharp on the subject’s eye. Eye AF support for animals[vii] will be added in Summer 2019 via a system software update, ideal for wildlife photographers.

 Video recording is 4K (UHD) and we think it's max 30FPS (it's not clear from Sony's information whether there are any higher rates but HD is up to 120 fps, which would equal the data rate of 4K at 30 fps, so this seems consistent). 

The camera includes an HLG mode for "instant HDR". The idea is that you can play your footage and see credible HDR on a suitable TV without any post processing. If you want to delve deeper into post, S-Log2 and S-log3 are supported. 

There is a headphone output. It's not clear what the audio input options are but we suspect it's via the smart-shoe, which would support the normal range of Sony microphone options. 

 This looks like an extremely interesting and capable camera. It's fascinating to see that Sony is explicitly aiming this at video bloggers. This is an already huge and growing category of users that need a small, inexpensive but high quality camera like this
