Sony a6400 review
Sony's a6400 is a compact 24MP mirrorless interchangeable lens camera with an APS-C sensor that will serve plenty of photographers from family documentarians to pro shooters looking for a lightweight second body. The big news is that it has a new processor based on that used in Sony's sports-shooting flagship a9 which enables 'Real-Time Tracking' autofocus, which is one of the most effective autofocus implementations we've yet seen. It's also among the easiest to use, once you've gotten it set up.

The Sony a6400 officially replaces the older a6300: it uses the same sensor but comes with some subtle enhancements aside from the impressive autofocus capabilities. It arrives in an increasingly crowded field, though, with cameras like the X-T30 from Fujifilm and the EOS M50 from Canon being similarly priced and with similar sized sensors. Do the enhancements make the a6400 the standout in this crowd? Find out its strengths - and weaknesses - in the pages to follow.
The a6400 is available now for $899 (€1049) body-only, $999 (€1149) with a 16-50mm F3.5-5.6 Power Zoom kit lens and $1299 (€1449) with an 18-135mm F3.5-5.6 zoom.
