A6400vs A7 V
VS
GearScore™ Verdict — 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.
Portrait, Wedding, Travel, Video — A7 V (2024): The definitive full-frame mirrorless. Hard to argue for anything else at this price.
