Sony Alpha a6400 Black 2019
The 24.2MP APS-C sensor paired with Real-time Eye AF and 0.02-second autofocus acquisition across 425 phase-detection points delivers sharp 11fps bursts that keep moving subjects in focus. At just 359g with weather sealing and a tilting touchscreen, it remains highly portable while offering S-Log profiles for graded 4K video and built-in Wi-Fi/Bluetooth. This camera is best for streamers and vloggers needing dependable face-tracking autofocus and 4K recording with color grading flexibility.
