The α6400 features the world’s fastest autofocus acquisition speed of 0.02 seconds, according to Sony, and has the newest advanced real-time eye AF and real-time tracking features that make shooting high-speed objects even more possible.

High-speed technology for high-speed moments: 

Capture quickly-moving subjects with ease, thanks to the new autofocus system that features an AF acquisition speed of 0.02 seconds and 425 phase- and contract-detection AF points that cover nearly 84 percent of the image area, locking onto a subject and tracking them throughout movement. 

The addition of the Real-time Eye AF, which uses AI to detect and process the data in real time, means users can focus on the eye of their subjects (you can even choose a preferred eye) throughout fast-moving scenes. Eye AF for animals will also be coming via a software update this summer.  

The Real-time Tracking feature uses AI, depth, and brightness to detect and track subjects throughout the frame. The α6400 has shooting speeds up to 11fps with full AF/AE tracking and mechanical shutter. Employ silent shooting and the α6400 can shoot up to 8fps with full AF/AE tracking.

High-resolution 4K recording: 

For videographers and bloggers, the Sony α6400 includes internal high-resolution 4K movie recording with full pixel readout and no pixel binding, Sony notes. An interval recording feature for time-lapse movies can be programmed from one to 60 seconds, capturing up to 9,999 shots. 

The new addition of Hybrid Log-Gamma (HLG) picture profile means you can use an Instant HDR workflow during playback.
