Sony Alpha 6400 review

Sony Alpha 6400 is the pick on this list for moving subjects. Sony says its 0.02 second autofocus was the fastest among APS-C interchangeable lens cameras as of January 2019, using 425 phase-detection points that cover about 84% of the image area, plus Real-time Eye AF and Real-time Tracking. It shoots up to 11 fps with AF/AE tracking in Hi+ mode, which suits kids, dogs and youth sports. The 24.2MP APS-C Exmor CMOS sensor works with the BIONZ X engine, and internal 4K UHD at up to 30p is oversampled from about 6K. The touchscreen tilts 180 degrees for selfies, and Wi-Fi, NFC and Bluetooth handle transfers to a phone. Sony Electronics listed the body at $1,099.99 when we checked, with kits that add a 16-50mm or 18-135mm power zoom. The downsides are age, a body only price that needs a lens on top, and a clip limit of about 29 minutes. We compared documented features and published prices; we did not test the camera.
