Sony a6400

24MP APS-C sensor | Hybrid AF system | 4K video capture

What we like:

  • Impressive autofocus capability
  • Promising JPEG and Raw image quality
  • Oversampled 4K video

What we don't:

  • Ergonomics are hit and miss
  • No in-body stabilization
  • Noticeable rolling shutter in video
The a6400 is Sony's midrange 24MP mirrorless camera. It offers a broad range of still image and video features but with more dependable and easier-to-use autofocus system, making it a friendlier camera to use than the existing models.
The camera gives a reasonable level of direct control (though you need to adjust your hand to use one of the dials) and extensive customization, which minimizes the need to use its rather complex menus. The rear touchscreen can be used to set the AF point and flips up for selfies.
The a6400 offers great image quality, but now in a less expensive and easier-to-use package
The a6400's autofocus system can be impressively simple: reliably tracking whatever you point it at and making accurately focused people photos especially easy. This, combined with a high burst speed make it great for capturing key moments. Battery life is pretty reasonable for such a small camera.
The a6400's JPEGs show excellent detail and have improved color, giving attractive final output. The Raw performance remains strong, giving plenty of processing flexibility.
The a6400 shoots highly detailed 4K video but shows significant rolling shutter (a form of distortion of horizontal movement), and a crop in 30p mode. There's an impressive array of video tools to help you shoot creative clips but there's no headphone output for monitoring audio.
The simple-to-use autofocus is the a6400's strongest feature, making it comparatively easy to make use of its full capability to shoot great images. The video is no longer cutting edge, and the ergonomics won't be to everyone's taste, but overall the a6400 is a hugely capable camera that delivers results.
