Sony Alpha a6400 Black 2019
The 24.2MP APS-C sensor and Real-Time Eye AF with 425 phase-detect points deliver a 0.02-second focus lock, making it exceptionally responsive for stills at 11fps. Its compact 358g weather-sealed body houses a 2.36m-dot OLED viewfinder and a 180° tilting touchscreen, offering strong value for a hybrid shooter without stabilization. This camera is best for beginner photographers and event shooters who prioritize fast, reliable autofocus over in-body stabilization.
