Love it. Great camera.

Sony’s latest APS-C mirrorless features some remarkable technology, says Andy Westlake, but is let down by its out-dated body design.

Astonishingly capable subject-tracking autofocus; Excellent image quality in almost any shooting situation; High level of control customisation available; Relatively compact size and decent build quality; Astonishingly capable subject-tracking autofocus; Excellent image quality in almost any...

Out-dated body design is much less pleasant to use than its competitors; Control setup is poorly-configured out of the box; 16:9 LCD screen gives small display area for 3:2 stills; Minimal touchscreen functionality; No in-body image stabilisation; Out-dated body design is much less pleasant to use...

The Sony A6400 is easily the best example of the highest-quality available in the market. It’s an extraordinary value for the money and is a great addition to the Sony A7-series because of its wonderful features.

Tilting LCD screen for vlogging; Built-in flash and limitless recording; Fast and responsive autofocus system; Updated button for spontaneous control; Multiple video functions for any type of movie

External controls are limited; Battery is not very long-lasting; Menu system is not easy to maneuver

Sony Alpha 6400 is a great video camera and not because it can shoot in 4K. Every camera does that now....

The A6400 is a strong performer in terms of all-round image quality, general speed and autofocus, and its small size makes it easy to live with – but we can’t help feel that some of Sony’s choices might be enough to put off potential buyers. The lack of in-body stabilisation, the upwards-flipping screen potentially being blocked by an external mic and the very noticeable rolling shutter appearance in videos are all black marks against an otherwise impressive camera. None of them make the A6400 a bad buy, but they do mean you might be better off with another mid-range model.

Lightning fast, super accurate autofocus; Small, lightweight body; Generally strong all-round image quality;

Some awkward ergonomic choices; No in-body stabilisation; Very visible rolling shutter effect;

The Sony A6400 offers fantastic specifications for the price and features. Highlights include excellent auto-focus tracking, a compact travel design and a diverse set of compatible accessories and lenses. Were it not for minor issues with its handling and battery life this would be one of the best mid-level mirrorless cameras around.

Fantastic AF tracking; Small size is great for travelling; Good range of accessories and lenses;

Fiddly operation; Limited battery life; Viewfinder and screen using old technology;

The Sony a6400 is a near-universally capable midrange camera that offers some of the best autofocus performance we've ever seen, backed up by solid image and video quality in most situations. We'd really like to see some further refinement on ergonomics, as Sony has done with its full-frame models over the years, but the a6400 remains an excellent option for a variety of types of photography.

Family and social photography, fast action and sports, world travelers and anyone looking for the best autofocus bang-for-your-buck.;

Those photographers seeking a more engaging or more fun shooting experience, those with larger hands and shooters that need consistently pleasing auto white balance in their JPEG shooting;

Faster, brighter and a little vainer, the A6400 is a great little camera for the creative photographer and videographer. It builds on the success of its predecessors with a very accomplished focus tracking system, fast focus and more adaptable tilting rear screen.

Lacks built-in stabilisation of A6500; Top rather than side tilting screen; Screen blacks out at top burst setting; Menu system still seems cluttered; Slow start-up with power zoom; Rolling shutter issue at 4K;

It’s great that Sony has put the work in on the autofocus system for the A6400. It’s something that can really help photographers of all levels. Real-time Tracking aside, it’s not quite as fast or as reliable as the AF system in the Sony A9, but it’s very good, especially for a camera that is set to...
