Sony Alpha a6400

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 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...

Highly advanced autofocus ; Decent burst shooting speed ; Bright viewfinder ; Good video features ; Good value for the spec

No built-in image stabilization ; No headphone jack ; 16:9 aspect ratio screen

You could be forgiven for thinking that the Alpha A6400 is a minor upgrade over the A6300, and in many ways it is. But it's the upgraded and highly advanced autofocus that really shines here, even more so given that it's on a camera costing under...

Subject tracking AF system ; 180 degree tilting LCD screen for front of camera viewing ; Button and dial customisation ; Great low light performance ; Highly accomplished metering ; Pro video outputs and control

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

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...

Excellent picture quality ; Small and transportable ; Great video quality

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

A handful of key issues prevent Sony’s small, fast shooter from being a resounding triumph

Great autofocus features ; Selfie mode ; Video and still shooting options

Some button and design layout issues ; No built-in stabilization

The compact size of the Sony Alpha A6400 makes it a great choice for travel compared to a larger full-frame camera. Image quality is impressive, with the camera delivering great image quality, with improved noise performance. The 18-135mm lens performs...

Excellent eye- and face-tracking autofocus ; Fast burst shooting speeds ; Improved programmable buttons ; Sharp video

Bad rolling shutter ; No in-body stabilization ; Dated sensor ; No headphone port

It's hard to overstate just how good the autofocus system is on the Sony a6400. It's got one of the best implementations out there: not just in its price range, but on the market, period. Once you set the system up, you can pretty much leave it alone...
