Sony Announces the Brand New a6400

  By Kaitlyn Kerr


Sony has announced the a6400, a brand new APS-C camera. Equipped with a 24.2 megapixel sensor, and a brand new BIONZ X processor, the latest addition to the lineup is the first APS-C camera to inherit many of the autofocus technologies present and popular in their full frame lineup models such as the a9, a7R III and a7 III. This camera is capable of locking focus in as little as 0.02 seconds, with Sony calling it the fastest APS-C camera in the world (as of writing).

With 425 phase-detect autofocus points covering approximately 84% of the image sensor, the a6400 introduces a new Real-time tracking, an autofocus tracking mode powered by artificial intelligence (AI) based object detection. This technology processes colour, subject distance and pattern (brightness) as spatial information to better track subjects with accuracy. The a6400 will have Real-time Eye AF, a similarly-improved version of the popular Eye AF mode powered by this AI technology. Eye-AF is now activated by a half-press of the shutter button in all autofocus modes, and the preferred (left or right) eye can now be chosen as a focus point.

Eye-AF for animals is also expected to be added to the camera via a firmware update expected in the summer of 2019.

These new tracking modes, combined with the new BIONZ X processor make the camera a formidable player where fast autofocus is concerned. The camera will shoot, with full autofocus tracking, up to 11 frames per second, or 8 frames per second in complete silence. 

For video, the a6400 can record internal 4K with a full sensor readout and no pixel binning. Full HD can also be recorded up to 120fps (at 100Mbps) for slow-motion footage. This is also the first APS-C camera from Sony to include an HLG (Hybrid Gamma-Log) picture profile, standard for HDR video capture. Included as well is an intervalometer for shooting time-lapses, which can be set to anywhere from 1-60s intervals for 1-9999 images. A fully 180-degree articulated touch LCD screen has also been included.  

The camera will being shipping this spring, in body only ($1249.99), and kit configurations with the 16-50mm PZ ($1349.99) or the 18-135mm lenses ($1749.99).
