Which should you buy?
Portraits, Street & Everyday — Canon RF 50mm f/1.8 STM (2020): The essential first prime for Canon RF shooters — f/1.8 background separation at an accessible price with near-silent STM autofocus.
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.
