Sony announced the Sony Alpha A6400 on January 12, 2019. This mirrorless camera is the successor to the A6300 and has therefore received the necessary updates and improvements. The A6400 has become a lot faster in terms of focusing and is suitable for vlogging. A nice new camera from Sony, but unfortunately there is no built-in image stabilization.
Like the Sony A6300 and A6500, this camera has a 24.2-megapixel APS-C sensor. As in the A6500, a front-end LSI chip speeds up internal processing. Together with the updated BIONZ X processor, this improves high-ISO performance and increases the continuous-shooting buffer.
The A6400 is equipped with the latest AF system and can focus in just 0.02s. The A6300 and A6500 need 0.05 seconds for this. The A6400 also has a new algorithm that improves tracking of moving subjects; the camera detects the subject based on its color, pattern (brightness), face and eye information.
EyeAF, which uses a single phase detection point on your subject's eye, now also works when you press the shutter button halfway.
Vloggers have become a big market for camera manufacturers and Sony is also keen to serve this demographic. That is why the Sony Alpha A6400 is equipped with a display that can be aimed at yourself. This allows you to clearly see whether you are within your frame and whether the focus is working properly.
Unfortunately, the camera lacks in-body image stabilization, but that can easily be overcome. Many Sony lenses have built-in stabilization and automated gimbals stabilize wonderfully and provide a good hold.
The improvements were not especially large compared with the A6500, but the A6400 succeeded the A6300—and the differences there were considerable, especially for Sony’s entry-level APS-C model. At the time, Sony was therefore expected to introduce the A6500’s successor later that year.
