Which should you buy?
Professional Sports, Wildlife & Photojournalism — EOS R1 (2024): Canon's ultimate professional camera — 40fps, a class-leading EVF, and AI AF that simply doesn't miss.
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.
