Which should you buy?
Professional Hybrid Shooters, Portrait & Wildlife — EOS R5 (2020): A landmark camera — 8K video and 45MP in one body set the standard for what mirrorless could be.
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.
