A6400vs A7 II
VS
Which should you buy?
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
Travel, Portrait — A7 II (2014): The camera that proved full-frame IBIS was possible in a compact body.
