Sony's Alpha a6400 is not a full-frame camera but it has plenty of features you'd associate with one. This makes this APS-C-format mirrorless camera a great choice if you’re serious about photography, but shopping within a set budget.
The autofocus system has the same technology as Sony's full-frame models, such as the renowned a9. 425 phase-detection AF points, and 425 contrast-detection AF points, cover around 84% of the image area. This combines with a BIONZ X image processing engine that lets you attain focus in just 0.02 seconds.
The BIONZ X processor plus a 24.2MP APS-C image sensor equals enhanced image quality and colour reproduction. Yet again, the Alpha a6400 has full-frame capability in this department, with image processing algorithms suppressing noise and preserving image resolution.
The Alpha a6400 is fantastic for movie-making. The 4K UHD recording process results in high-quality 4K video footage with sharp detail and excellent depth. Vloggers like the camera for this very reason.
Shoot with greater freedom, thanks to features like the 180° 3.0" LCD tiltable flip screen with 921,600 dots of resolution; this allows for effective framing of selfie-style shooting for still and video capture.
The lens is one of the most important features in any camera, and it's a standout in this model. The E 18-135mm f/3.5-5.6 OSS lens spans the wide-angle to medium telephoto range, and is partnered with a 27-202.5mm equivalent zoom and Optical SteadyShot image stabilization feature, which vastly reduces camera shake during handheld shooting.
A newer model Sony Alpha A6500 was released in October 2016.
