Sony today introduced an exciting new addition to its E-mount mirrorless camera lineup – the α6400 (model ILCE-6400).


The α6400 brings many of Sony’s most advanced technologies from their acclaimed full-frame lineup to a compact, lightweight APS-C camera. The speedy new camera boasts the world’s fastest1 autofocus (AF) acquisition of 0.02 seconds2, while also introducing the new advanced “Real-time Eye AF” and ”Real-time Tracking” capabilities. Also included are high-speed shooting at up to 11 fps4 with AF/AE tracking, a new-generation BIONZ X image processing engine that produces excellent image quality, 4K6 video recording, a fully 180-degree tiltable LCD touch screen and much more, making it the ultimate tool for all types of creators ranging from professionals to everyday vloggers.


Speedy Performance that Captures Decisive Moments The impressive autofocus system on the new α6400 inherits many technologies from Sony’s newest line-up of full-frame cameras including the α9, α7R III and α7 III models. The new camera features 425 phase-detection AF points and 425 contrast-detection AF points that are placed densely over the entire image area, covering approximately 84% of the image area. This high-speed, high-performance tracking AF system is paired with a new-generation BIONZ X image processing engine that together allows the camera to acquire focus in as little as 0.02 seconds2 and maintain subject lock extremely effectively, ensuring even the fastest moving subjects can be tracked and captured with ease.


The α6400 introduces advanced “Real-time Eye AF,” the latest version of Sony’s acclaimed Eye AF technology. This exciting new capability employs artificial intelligence (AI) 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 is able to 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 will be added in summer 2019 via a system software update, ideal for wildlife photographers.


Also debuting on the α6400 is Sony’s newly developed “Real-time Tracking.” This mode utilises Sony’s latest algorithm including artificial intelligence (AI) based object recognition and processes color, subject distance (depth), pattern (brightness) as spatial information to ensure that all subjects can be captured with excellent accuracy. Additionally, when photographing or videoing humans or animals, face and eye position information is recognised by AI and the subject’s eye7 is monitored in real time with extremely high tracking precision. This can be activated by a simple half press of the shutter button , or can be assigned to a custom function as well.
