Characteristics in general

Capture the Moments That Make a Difference

Many of the innovations seen in Sony’s full-frame cameras, such as the a9, a7R III, and a7 III models, are carried over to the a6400’s focusing system. In all, there are 425 phase-detection AF points and 425 contrast-detection AF points on the a6400, which are distributed densely throughout the whole picture area, accounting for about 84 percent of the total image area.

In conjunction with a BIONZ X image processing engine, this high-speed, high-performance tracking AF system allows the camera to acquire focus as quickly as 0.02 seconds and maintain subject lock effectively, ensuring that even the fastest moving subjects can be tracked and captured with ease, regardless of their speed.

Advanced “Real-time Eye AF,” the most recent version of Sony’s Eye AF technology, is included in the new a6400 camera. In order to identify and analyze eye data in real-time, this functionality makes use of artificial intelligence-based object identification, which results in better accuracy, speed, and tracking performance of Eye AF.

If the subject’s eyes are detected, the camera immediately activates Eye AF with a half-press of the shutter button. When in AF-C or AF-A mode, the preferred eye of your subject (either left or right) may be selected as the focus point.

Auto, Right Eye, and Left Eye are available as options, and a Switch Right / Left Eye function can be applied to a custom function as well as a standard function. As a result of this technology, the photographer may concentrate only on composition, confident that the focus will be razor-sharp on the subject’s eye.

The addition of eye AF support for animals will be made possible by a system software upgrade in the summer of 2019.

Sony’s “Real-time Tracking” technology makes its debut on the a6400 as well. To guarantee that all subjects can be caught with precision, this model makes use of Sony’s technology, which integrates artificial intelligence (AI) based object identification and analyses color, subject distance (depth), and pattern (brightness) as spatial information.

Additionally, whether photographing or videotaping individuals or animals, artificial intelligence recognizes their faces and eye positions, and the subject’s eye is watched in real-time with high tracking precision, allowing for more accurate results. Activation can be accomplished with a simple half-press of the shutter button, or it can be assigned to a specific function.

To give you an idea of the camera’s total shooting speed, it can shoot at up to 11 frames per second with complete AF/AE tracking while using the mechanical shutter, and at up to 8 frames per second with full AF/AE tracking when shooting silently. It can shoot at each of these speeds for up to 116 frames JPEG Standard / 46 frames raw compressed, considerably boosting the likelihood of capturing the perfect moment…

Improvements in the quality of images

Cameras such as the Sony a6400 are equipped with a 24.2MP APS-C picture sensor that is combined with an enhanced BIONZ X engine to give greater image quality and color reproduction in a variety of shooting environments.

It is possible to shoot still photos and movies with standard ISO ranges of up to 32,000 for still images and movies with standard ISO ranges of up to 102,400 for still images. The ISO ranges are suitable for noise reduction at medium and high sensitivities.

4K video recording with fast hybrid autofocus is available.

The versatile a6400 is a solid video camera that records internal 4K UHD (3840 x 2160) movies with full pixel readout and no pixel binning to collect approximately 2.4x the amount of data required for 4K movies and then oversamples it to produce high-quality 4K footage with detail and depth.

The a6400 is also capable of shooting a 4K video in RAW format. The updated Fast Hybrid AF technology, which maintains the subject in continual smooth focus even when an object crosses in front of the camera, makes focusing during video shooting both quick and steady.

This camera’s powerful autofocus system, along with the touch focus feature, makes it an excellent choice for many vloggers and video makers who routinely create and publish material on the internet.

The camera has built-in interval recording that can be set anywhere between 1 and 60 seconds, with a total number of images ranging from 1 to 9999, which may be used to create time-lapse movies with the camera.

During interval shooting, the AE tracking sensitivity may be set to “High,” “Mid,” or “Low,” allowing for less variation in exposure over the course of the shooting interval, which is beneficial.

Aside from that, this model offers an HLG (Hybrid Log-Gamma) picture profile, which allows an Instant HDR process, allowing HDR (HLG) compatible TVs to replay breathtaking, true-to-life 4K HDR pictures for the first time in a Sony APS-C mirrorless camera.

Furthermore, both S-Log2 and S-Log3 are offered for enhanced color grading freedom, as well as Zebra capabilities, Gamma Display help, and proxy recording, to name a few other features. Aside from that, the camera can record in Full HD at 120 frames per second at up to 100 megabits per second, allowing footage to be examined and subsequently converted into 4x or 5x slow-motion video files in Full HD quality with autofocus tracking.
